摘要

本文通过计算机仿真研究了宽带码分多址(WCDMA)中非线性光学子系统和线性时变射频信道对系统误码率(BER)性能的影响。这些影响通过导频辅助估计和均衡方法在不同的输出回退(obo)水平进行补偿。误码率图表明，即使在最大非线性(0.0 dB OBO)下，该方法也是一种有效的策略。

BER assesment of a WCDMA-based Radio-over-Fiber system using a pilot-aided estimation and equalization approach

In this paper we assess the effects of nonlinear optical subsystem and linear time variant RF channel of Radio-over-Fiber (RoF) in Wideband Code Division Multiple Access (WCDMA) on the system bit error rate (BER) performance by computer simulations. These effects are compensated by pilot aided estimation and equalization approach at different Output Back-Off (OBOs) levels. BER plots show that this approach is an effective strategy even at maximum nonlinearity i.e. 0.0 dB OBO.
