基于区域的层次结构链接状态协议 (ZHLS)

实现了TD,GPRS,EDGE通信系统中物理层部分需要用到的打孔和解打孔算法，非常实用，并且已经应用到了实际的基站实现中-realize the algorithms of puncture and depuncture in the TD,GPRS,EDGE system,very very useful

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.

QAM调制的基本原理 QAM调制实际上是幅度调制和相位调制的组合。相位 + 幅度状态定义了一个数字或数 字的组合。QAM的优点是具有更大的符号率，从而可获得更高的系统效率。通常由符号率 确定占用带宽。因此每个符号的比特（基本信息单位）越多，效率就越高。-QAM modulation of the basic principles are in fact QAM modulation amplitude modulation and phase modulation of the portfolio. Phase+ margin status defines a combination of numbers or figures. The advantage of QAM symbols are greater rate, thus the system efficiency will be higher. Symbol rate is usually determined by the occupied bandwidth. Thus each bit symbols (basic units of information) the more the higher the efficiency.
