Abstract

In land mobile to mobile (LMM) channel, random frequency shifts (RFSs) may be introduced into the carrier frequency as a result of the Doppler effect due to the motion of transmitter (Tx) and receiver (Rx). Hagras et al. (2000) showed that the performance of center sampling differential detection (CSDD) in an LMM channel yields poor performance in the presence of RFSs. The main object of this paper is to study the performance of center sampling double differential detection (CSDDD) scheme introduced in Abdelkader and Fred (1986) in an LMM channel and compare its performance with the CSDD scheme. The performance of the CSDD and CSDDD schemes are analyzed in a two path Rayleigh fading channel taking into account frequency selective fading (FSF), RFS, intersymbol interference (ISI), Doppler frequency shift, cochannel interference (CCI), and additive white Gaussian noise (AWGN). It is shown that the CSDDD scheme in the LMM channel has the potential to compact the effect of RFS and its performance is better than the CSDD scheme when RFSs are introduced into the carrier.

基于CSDD和CSDDD方案的GMSK在随机频移和CCI的陆地移动到移动信道中的性能分析

在陆地移动到移动(LMM)信道中，由于发射机(Tx)和接收机(Rx)的运动而产生的多普勒效应，可能会在载波频率中引入随机频移(rfs)。Hagras等人(2000)表明，在rfs存在的情况下，LMM通道中的中心采样差分检测(CSDD)性能较差。本文的主要目的是研究Abdelkader和Fred(1986)提出的中心采样双差分检测(CSDDD)方案在LMM信道中的性能，并将其与CSDD方案的性能进行比较。考虑频率选择衰落(FSF)、RFS、码间干扰(ISI)、多普勒频移、同信道干扰(CCI)和加性高斯白噪声(AWGN)等因素，分析了CSDD和CSDDD方案在双径瑞利衰落信道中的性能。结果表明，LMM信道中的CSDDD方案具有压缩RFS效应的潜力，在载波中引入RFS时，其性能优于CSDD方案。
