Analysis of Multilevel-Quantized Soft-Limiting Detector for an FH-SSMA System
Abstract: In this paper, a multilevel-quantized soft- limiting (SL-MQ) detector for frequency hopping spread spectrum multiple access (FH-SSMA) system is proposed and analyzed. Numerical and simulation results in frequency selective Rayleigh fading channels show that as compared to the hard-limiting (HL) detector, the new SL-MQ with Å can improve the system capacity by almost ½¼± at the bit error rate level of ½¼ ¿. Furthermore, the performance of the SL-MQ has low sensitivity to the optimum value of the amplitude threshold so that it can tolerate inaccurate estimate of its optimum in practice.
