基于OpenH323的一个VoIP程序，下载自国外专业网站-based on OpenH323 of a VoIP procedures downloaded from the website abroad

此程序为非二进制LDPC 码的仿真程序. 信道为AWGN, 调制方式 是BPSK.-This program is used to simulation nonbinary LDPC codes over AWGN channel and BPSK modulation. The decoding algorithm is in the probability domain and with the fast Hadamard transform in the check node.

生成2KHz和8KHz的混合信号，使该信号通过上述滤波器，观察滤波前后的波形变化和频谱分布情况。 在改信号中加入高斯白噪声，观察滤波前后的波形变化和频谱分布情况。-2KHz and 8KHz generation mixed-signal, so that the signal through the above-mentioned filter, filter before and after observation of the waveform and spectrum distribution of the changes. Add to the signal in white Gaussian noise was observed before and after filtering the waveform and spectrum distribution of the changes.
