BIT ERROR RATE AND SIGNAL-TO-NOISE RATIO that have errors relative to the total number of bits received in a transmission. The different modulation techniques scheme is In telecommunication transmission, the bit error rate (BER) suggested for improvement of BER in fiber optic is the percentage of bits that have errors relative to the total communications. The developed scheme has been tested on number of bits received in a transmission. For example, a optical fiber systems operating with a non-return-to-zero (NRZ) transmission might have a BER of 10-6, meaning that, out of format at transmission rates of up to 10Gbps. Numerical 1,000,000 bits transmitted, one bit was in error. The BER is simulations have shown a noticeable improvement of the system an indication of how often data has to be retransmitted BER after optimization of the suggested processing operation on the detected electrical signals at central wavelengths in the because of an error [1].

  • Digital Quality Index (DQI) Assessing Downstream Digital Signal Quality
    VIAVI Solutions Application Note Digital Quality Index (DQI) Assessing Downstream Digital Signal Quality Overview Most downstream channels are transported on digital quadrature amplitude modulation (QAM) carriers. How are intermittent transport issues detected within those downstream digital services, and are customer quality expectations being met? A patented VIAVI measurement called DQI (Digital Quality Index) concentrates on the condition of the raw information on the physical path and immediately detects intermittent issues and sustained issues within the stream. In comparison, the typical measurement used to check for these issues on a digital QAM carrier is pre and post forward error correction (FEC) bit error ratio (BER), which relies on actual errors and is relatively slow to detect many issues. Drawback of Current Methods Most digital field test equipment today incorporates the same digital hardware components that reception equipment uses. These components use numerous correction technologies to adjust the demodulated carrier correcting problems that were the result of transmission issues on the RF physical path. These technologies make the digital reception a superior quality service versus the older analog methods. Test instruments monitor these technologies to achieve a quantitative view of how hard the reception hardware is working to correct the physical path issues. The resultant measurements become an indicator of potential issues, not actual carrier quality. In some cases, the technologies can mask the issues since their intent is to correct issues before the user sees a problem. Utilizing the same technologies for test purposes is not as responsive as the old analog test measurements. What is the Goal of Field Testing? The goal of field testing is to identify network issues before services are affected and to fix the problem before the customer experiences any degradation of service.

  • MODULATION ERROR RATIO by RON HRANAC
    Originally appeared in the January 2007 issue of Communications Technology. MODULATION ERROR RATIO By RON HRANAC Awhile back I went target shooting with a friend. While at the range, it occurred to me that what is also known as plinking is a little like modulation error ratio (MER) used to characterize, say, the 64- and 256-QAM (quadrature amplitude modulation) digitally modulated signals we transmit to our customers. OK, before you start to wonder whether I’ve had too much coffee today, bear with me as I discuss this somewhat off-the-wall analogy. Similarities A typical target used at the range comprises a set of concentric circles printed on a piece of paper. The center of the target is called the bull’s-eye, which carries the highest point value. The further away from the bull’s-eye, the lower the assigned points. Ideally, one would always hit the bull’s-eye and get the maximum possible score. In the real world, this seldom happens. Instead, one or two shots might hit at or near the bull’s-eye, and most of the rest hit somewhere in the circles surrounding the center of the target. For a person who is a decent shot, plinking usually results in a fairly uniform “fuzzy cloud” of holes in and around the bull’s-eye. The smaller the diameter of this cloud and the closer it is to the bull’s-eye, the higher the score. Factors affecting how close to the bull’s-eye the shots land include the quality and accuracy of the firearm, type of ammunition used, weather conditions if outdoors, ambient lighting, and the distance to the target.

  • CNR VERSUS SNR by RON HRANAC
    Originally appeared in the March 2003 issue of Communications Technology. BROADBAND: CNR VERSUS SNR By RON HRANAC A recent discussion on the SCTE-List is the basis for this month's column. The discussion had to do with the difference between carrier-to-noise ratio (C/N ratio or CNR) and signal-to-noise ratio (S/N ratio or SNR), and whether or not the Data Over Cable Service Interface Specification (DOCSIS) includes an upstream SNR spec in addition to the recommended 25 dB CNR spec. Let's look at the last question first. Table 2-2, "Assumed Upstream RF Channel Transmission Characteristics," from the DOCSIS 1.0 Radio Frequency Interface Specification summarizes recommended upstream performance for reliable data transmission on a cable network. Among the parameters in that table are carrier-to-noise, carrier-to-ingress power and carrier-to-interference ratios, all of which are supposed to be "not less than 25 dB." SNR is not mentioned. In the world of telecommunications, SNR and CNR often are used interchangeably. I dug out Roger L. Freeman's Telecommunications Transmission Handbook, 2nd Ed. (John Wiley & Sons, Inc., ©1981, ISBN 0- 471-08029-2). Freeman says, "The signal-to-noise ratio expresses in decibels the amount by which a signal level exceeds its corresponding noise." Another reference, Measuring Noise in Video Systems (Tektronix Application Note 25W-11148-0, ©1997), says, "In the most general case, SNR is expressed as the ratio of rms (root mean square) signal level, Srms, to the rms noise, Nrms, (SNR = Srms/Nrms)." In the world of cable, we tend to use CNR and SNR to represent quite different measurement parameters, one in the RF domain and the other in the baseband domain.
