摘要

在(Cavallini, et al.，(1997))中，已经提出并研究了在频率非选择性快衰落信道中的芯片级差分检测。然而，在多径瑞利衰落信道中，对其性能的研究还很少。在本文中，我们评估了多径信道对两种芯片级差分检测性能的影响。通过仿真研究了误码率的计算结果。并对传统符号级差分检测的性能进行了比较研究。

Performance of chip-level differential detection for DS-CDMA in multipath fading channels

Chip-level differential detection has been proposed and studied in frequency-nonselective fast fading channels in (Cavallini, et al., (1997)). However, the performance in multipath Rayleigh fading channels has not been studied so far. In this paper, we evaluate the impact of multipath channels on the performances of two types of chip-level differential detections. The bit error rate (BER) results are investigated via simulations. The performance of a conventional symbol-level differential detection is also studied as a comparison.
