چکیده
Abstract: In this paper, a multilevel-quantized softlimiting (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 can improve the system capacity by almost at the bit error rate level of . 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.

Iterative decoding in convolutionally and turbo coded MFSK/FH-SSMA systems
This paper presents an iterative decoding method in the coded MFSK (multilevel frequency shift keying)/FH-SSMA (frequency hopping-spread spectrum multiple access) system. The kernel of the system, which is a symbol APP (a posteriori probability) calculator, accepts channel values and a priori information from the channel decoder and generates reliability values of the received symbols. The chan...
متن کاملMultiuser demodulation and iterative decoding for frequency-hopped networks
Demodulation and decoding for frequency-hopped spread-spectrum multiple-access (FH/SSMA) systems have been traditionally conducted by conventional single-user (noncollaborative) demodulation and errors and erasures correcting decoding techniques. In this paper, we study the demodulation and decoding aspects of collaborative multiuser reception for FH/SSMA and propose methods which increase the ...
متن کاملTurbo Codes with Channel Estimation and Dynamic Power Allocation for Anti-Jam FH/SSMA *
In this paper we study the performance of turbo codes infrequency-hopped spread spectrum multiple access networks (FH/SSMA). An iterative scheme for estimating the log likelihood ratio of the channel output is proposed. This scheme is compared with other techniques that provide tradeoffs between simplicity of implementation, BER performance, and robustness to channel variations. Based on the es...
متن کاملPerformance Evaluation of Slotted ALOHA FH-SSMA Systems with Generalized Retransmission Backoff
In distributed spread-spectrum packet radio networks where the number of active users and the packet arrival rate may vary with time, an adaptive channel access protocol is necessary to avoid system saturation. In this paper, we present an analytical investigation of generalized retransmission backoff policies for slotted ALOHA FH-SSMA systems. In the backoff techniques, each user adapts the re...
متن کاملPartial successive interference cancellation in hybrid DS/FH spread-spectrum multiple-access systems
Partial successive interference cancellation is considered in hybrid DS/FH spread-spectrum multiple-access (SSMA) systems. We first show that the lowest BER attained by employing full interference cancellation in DS/SSMA systems can almost be achieved by employing a partial interference cancellation in hybrid DS/FH systems. The reduction in the number of cancellations translates into an allevia...
