In this paper, we analyze and compare the performances of different MIMO techniques. In particular, we compare the performance of three MIMO methods, namely, BLAST, STBC, and linear precoding/decoding. We provide both an analytical performance analysis in terms of the average receiver SNR and simulation results in terms of the BER. Moreover, the applications of MIMO techniques in WCDMA systems are also considered in this study. Specifically, a subspace tracking algo- rithm and a quantized feedback scheme are introduced into the system to simplify implementation of the beamforming scheme. It is seen that the BLAST scheme can achieve the best performance in the high data rate transmission scenario; the beamforming scheme has better performance than the STBC strategies in the diversity transmission scenario; and the beamforming scheme can be effectively realized in WCDMA systems employing the subspace tracking and the quantized feedback approach. Keywords and phrases: BLAST, space-time block coding, linear precoding/decoding, subspace tracking, WCDMA. 1.

These challenges can be partially overcome by using higher gain antennas, Multiple-Input Multiple-Output (MIMO), or beamforming techniques. Yagi-Uda antennas combine high gain with low cost and reduced size, and might result in compact and efficient antennas to be used in Internet of Thins (IoT) sensors. The design of a compact multilayer Yagi for IoT sensors is presented, operating at 24 GHz, and a comparative analysis with a planar printed version is shown. The stacked prototype reveals an improvement of the antenna’s main properties, achieving 10.9 dBi, 2 dBi more than the planar structure. In addition, the multilayer antenna shows larger bandwidth than the planar; 6.9 GHz compared with 4.42 GHz. The analysis conducted acknowledges the huge potential of these stacked structures for IoT applications, as an alternative to planar implementations. Keywords: Yagi-Uda; multilayered antenna; millimeter-waves; IoT 1. Introduction People’s interconnection was improved by 4G, making the communication more efficient, fluent, and natural.

Introduction To help engineers navigate the challenges of 5G OTA testing, LitePoint has put together this comprehensive guide to 5G OTA testing, featuring articles previously published at EDN, Microwaves & RF and RF Globalnet. Link-budget Calculations: Needed for 5G OTA Testing (page 3) In his article at EDN, LitePoint’s Jeorge Hurtarte explores how to calculate the total link budget for OTA test. Over-the-Air Testing for 5G mmWave Devices: DFF or CATR? (page 8) At Microwaves & RF Hurtarte and LitePoint’s Middle Wen explain the differences between DFF and CATR chambers and the tradeoffs in cost and path-loss performance between the two types of chambers. Understanding 5G Millimeter Wave Beamforming Test (page 14) Finally, in the article at RF Globalnet, Jeorge Hurtarte and LitePoint’s Vito Liao explain beamforming in the context of 5G NR specifications, and introduces beamforming characterization and beamforming verification test. Updated: May 20, 2019 LitePoint’s Complete Guide to 5G OTA Testing 2 Link-budget Calculations: Needed for 5G OTA Testing Previously published at EDN on January 22, 2019 5G millimeter wave (mmWave) devices operating above 24 GHz incorporate millimeter-sized patch antenna arrays or dipole antennas that become an integral part of the device module packaging. Testing these assemblies requires over-the-air tests inside a chamber. But, a mmWave test chamber can introduce significant path loss, more than from cables and connectors. Understanding how to calculate the total link budget for over-the-air testing is a critical step in 5G mmWave OTA test.

  • MIMO Fading Channel Capacity, Massive MIMO, Beamforming, Diversity Vs
    Lecture 15 - EE 359: Wireless Communications - Winter 2020 MIMO Fading Channel Capacity, Massive MIMO, Beamforming, Diversity vs. Multiplexing, RX Design Lecture Outline • MIMO Fading Channel Capacity • Massive MIMO • Beamforming • MIMO Diversity/Multiplexing Tradeoffs • MIMO RX Design 1. MIMO Fading Channel Capacity • In fading, capacity with both transmitter and receiver knowledge is the average of the capacity for the static channel, with power allocated either by an instantaneous or average power constraint. Under the instantaneous constraint power is optimally allocated over the spatial dimension only. Under the average constraint it is allocated over both space and time. • In fading, if the channel is unknown at transmitter, uniform power allocation is optimal, but this leads to an outage probability since the transmitter doesn’t know what rate R to transmit at: ρ H Pout = p H : B log2 det IMr + HH <R . Mt 2. Massive MIMO: • When the number of TX (or RX) antennas is large, the channel becomes “static” due to the law of large numbers. Specifically 1 H lim HH = IMr . Mt→∞ Mt • The MIMO channel capacity then becomes ρ H lim B log2 det IMr + HH = B log2 det [IMr + ρIMr ] = MrB log2(1 + ρ). Mt→∞ Mt • Defining M = min(Mt, Mr), this implies that as Mt grows large, the MIMO channel capacity in the absence of TX CSI approaches C = MB log2(1 + ρ) for ρ the SNR, and hence grows linearly in M. This is also true for finite Mt and Mr but at large SNR. 3. MIMO Systems: Beamforming • Beamforming sends the same symbol over each transmit antenna with a different scale factor.

  • Millimeter-Wave Evolution for 5G Cellular Networks
    1 Millimeter-wave Evolution for 5G Cellular Networks Kei SAKAGUCHI†a), Gia Khanh TRAN††, Hidekazu SHIMODAIRA††, Shinobu NANBA†††, Toshiaki SAKURAI††††, Koji TAKINAMI†††††, Isabelle SIAUD*, Emilio Calvanese STRINATI**, Antonio CAPONE***, Ingolf KARLS****, Reza AREFI****, and Thomas HAUSTEIN***** SUMMARY Triggered by the explosion of mobile traffic, 5G (5th Generation) cellular network requires evolution to increase the system rate 1000 times higher than the current systems in 10 years. Motivated by this common problem, there are several studies to integrate mm-wave access into current cellular networks as multi-band heterogeneous networks to exploit the ultra-wideband aspect of the mm-wave band. The authors of this paper have proposed comprehensive architecture of cellular networks with mm-wave access, where mm-wave small cell basestations and a conventional macro basestation are connected to Centralized-RAN (C-RAN) to effectively operate the system by enabling power efficient seamless handover as well as centralized resource control including dynamic cell structuring to match the limited coverage of mm-wave access with high traffic user locations via user-plane/control-plane splitting. In this paper, to prove the effectiveness of the proposed 5G cellular networks with mm-wave access, system level simulation is conducted by introducing an expected future traffic model, a measurement based mm-wave propagation model, and a centralized cell association algorithm by exploiting the C-RAN architecture. The numerical results show the effectiveness of the proposed network to realize 1000 times higher system rate than the current network in 10 years which is not achieved by the small cells using commonly considered 3.5 GHz band.

Karmakar, Senior Member, IEEE Abstract—A low-power consumption, small-size smart antenna, named electronically steerable parasitic array radiator (ESPAR), has been designed. Beamforming is achieved by tuning the load reactances at parasitic elements surrounding the active central element. A fast beamforming algorithm based on simultaneous perturbation stochastic approximation with a maximum cross correlation coefficient criterion is proposed. The simulation and experimental results validate the algorithm. In an environment where the signal-to-interference-ratio is 0 dB, the algorithm converges within 50 iterations and achieves an output signal-to- interference-plus-noise-ratio of 10 dB. With the fast beamforming ability and its low-power consumption attribute, the ESPAR antenna makes the mass deployment of smart antenna technologies practical.
