摘要

扩频(SS)技术似乎是传统窄带调制的一个有吸引力的替代方案。本文提出了一种基于慢跳频(SFH)的跳频系统模型。跳频模式以伪随机方式通过一组完全独立的信道。仿真了系统在加性高斯白噪声(AWGN)和瑞利衰落、Bose-Chaudhuri-Hocquenghem (BCH)编码和交织下/spl pi//4 DQPSK调制的误码率性能。同时考虑了同步干扰和异步干扰下的最佳交错尺寸和系统性能。

Bit error simulation of DQPSK for a slow frequency hopping CDMA system in mobile radio communications

Spread spectrum (SS) techniques seem to be an attractive alternative to conventional narrow-band modulation. In this paper a frequency hopping (FH) system model based on slow FH (SFH) is proposed. The hopping pattern is in a pseudo-random manner through a set of completely independent channels. The simulated results of the bit error rate (BER) performance of the system for /spl pi//4 DQPSK modulation in the presence of additive white Gaussian noise (AWGN) and Rayleigh fading, together with Bose-Chaudhuri-Hocquenghem (BCH) coding and interleaving are obtained. Consideration is given to the optimum interleaving size, and the system performance in presence of both synchronous and asynchronous interferers.
