Abstract
ABSTRACT
This paper is concerned with the improvement of the receiver operating characteristics. For this purpose, the received signal is interpreted as a cyclostationary process whose statistics vary periodically with time. Three types of detectors are considered. These detectors are the radiometer, the bit-rate single cycle detector, and doubled-carrier single cycle detector. It is found that, the performance of the bit-rate single cycle detector is better than the radiometer. Furthermore, the doubled-carrier single cycle detector is superior from the point of view of the obtained receiver operating characteristic. This result is referred to the fact that the accompanied additive white Gaussian noise (AWGN) to the desired signal is stationary process and it does not have cyclic spectrum component at any
cyclic frequency. Results indicate that, at S 5 dB, for a probability of false alarm of 2%, the radiometer has a probability of detection of 40%, the bit-rate single cycle detector has a probability of detection of 70%, and the doubled-carrier single cycle detector has a probability of detection of 93%.
