Analytical and simulated BER performance results for both carrier phase and bit synchronization timing errors were determined for serial and parallel demodulation. For a nonlimited modulated signal and ideal demodulator (no carrier phase or timing error), a BER degradation of 0.41 dB with respect to MSK performance is achieved for both serial and parallel demodulators with the sub-optimum data filter. A limited modulation signal increases the BER degradation by no more than 0.2 dB for both demodulator architectures. Serial demodulation is shown to be less sensitive to carrier phase error, while parallel demodulation offers less sensitivity to timing error. For both carrier phase and timing errors, the serial demodulator will provide less BER degradation than the parallel, if the timing error is kept small. Serial demodulation using average zero crossing bit synchronization is shown to provide either the same or less than a 0.1 dB increase in BER degradation as compared to that obtained with maximum eye opening synchronization. This result is significant, since average zero crossing synchronization is easily implemented in hardware.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121194666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Comparison of performance measures for intercept detectors","authors":"R. Rifkin","doi":"10.1109/TCC.1994.472091","DOIUrl":"https://doi.org/10.1109/TCC.1994.472091","url":null,"abstract":"The performance of intercept detectors is generally analyzed using the Neyman-Pearson criterion, which evaluates the probability of detection, P/sub d/, as a function of input signal-to-noise ratio (SNR) at a particular probability of false alarm, P/sub fa/. While the Neyman-Pearson criterion closely represents typical system requirements, it is often difficult to evaluate, and obscures important effects in tradeoff analyses. Consequently other performance measures, such as output SNR or the deflection, are often used instead. While the output SNR is useful for evaluating and optimizing a particular detector class, it may be inappropriate when applied to different detector classes. This paper examines the output SNR and probability of detection, for three intercept detectors: the radiometer, the chip rate detector, and the carrier harmonic detector (frequency doubler). The analysis makes the following assumptions: a direct-sequence pseudo-noise spread spectrum signal of interest additive stationary white Gaussian-distributed noise background with fixed known power (i.e., no noise power uncertainty) known power spectral density of the signal of interest input SNR much less than unity observation time much greater than the chip duration. The analysis highlights the danger of blindly evaluating detector performance solely by output SNR. Specific examples are identified in which the radiometer's performance, using the Neyman-Pearson criterion, is inferior to that of the cyclostationary feature detectors operating at equal output SNR for the decision variable.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115765241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
