| Abstract: | The performance of an asynchronous noncoherent hybrid direct sequence/frequency hopped spread spectrum communication system with a combined partial band noise (PBN), multiple access interference (MAI), nonselective slow Rician fading and additive white Gaussian noise (AWGN) will be analyzed in this paper. The performance of this scheme will be investigated against Rician fading, multiple access interference and partial band noise. The resulting effects of Rician fading, partial band interference, numbers of user, signal to noise rate and M of the MFSK modulation on performance of DS-SFH asynchronous noncoherent hybrid spread communication system will also be descried. |
