摘要

在多用户信道中，由于加性高斯白噪声(AWGN)和载波间干扰(ICI)，信号会被破坏。正交频分复用(OFDM)接收机检测符号或位并估计参数。小波包调制(WPM)应用于接收到的符号，这些符号之前已经在发射机用特殊的代码编码。最终得到的结果是降低了噪声(去噪)，从而提高了系统的误码率。

Strategies for Performance Evaluation of Wavelet Packet Modulation in Wireless Ad Hoc Networks

In a multiuser channel signals are corrupted due to Additive White Gaussian Noise (AWGN) and Inter Carrier Interference (ICI). Orthogonal Frequency Division Multiplexing (OFDM) receiver detects the symbols or bits and estimates the parameters. Wavelet Packet Modulation (WPM) is applied to the received symbols that have been previously coded at the transmitter by a special code. The final result obtained is a reduction of the noise (denoising), which results in performance improvement of bit error rate of the system.
