Abstract :
This paper examines the asymptotic performance of M-ary orthogonal modulation with noncoherent square-law detection and combining in Rayleigh fading. The analysis takes into consideration Reed-Solomon coding and evaluates the gain provided by the ratio-threshold test (RTT) which generates side information regarding the reliability of received symbols. The minimum received signal-to-noise ratio (SNR) required for error-free communication and the optimal code rate are derived for arbitrary orders of diversity. These asymptotic results are then extended to a direct-sequence code division multiple access (DS-CDMA) system with frequency-selective fading
