摘要:

通用Rice过程涵盖了从最深度衰落的单边高斯过程到比Rice过程更轻的衰落过程,与其他衰落模型相比具有更优异的性能.研究数字调制信号通过通用Rice信道传输的性能, 给出频率非选择性慢衰落通用Rice信道上相干二进制相移键控(BPSK)、相干二进制频移键控(BFSK)、差分相干二进制相移键控(DBPSK)和非相干二进制频移键控检测时的平均误比特率公式,分析了模型中各参量对平均误比特率性能的影响.

Abstract:

Generalized Rice process covers fading from the heaviest single-sided Gaussian process to the fading that is lighter than the Rice process. It has better performance than other fading channel models. This paper studies bit error rate (BER) performance of digital signals through a generalized Rice channel. Average BER of coherent binary phase shift keying (BPSK), coherent binary frequency shift keying (BFSK), differential binary phase shift keying (DBPSK), and non-coherent BFSK detection schemes for slowly fading non-frequency-selective channels is derived. Influence of all parameters in the generalized Rice model on average BER is investigated.

Key words: fading channel; channel model; generalized Rice process; bit error rate (BER)
