说明: 随着信息容量的增加和频率资源的稀缺,为提高单位频带利用率,在微波通信系统中越来越多地采用多电平多相位的复杂信号调制方式,尤其是正交幅度调制(QAM)得到了大量的应用,从早期的4QAM到今天的16QAM。高阶QAM调制大容量数字微波通信系统为了保证服务质量,降低误码率,(long with the increase of information capacity and frequency resource scarcity, for improving the utilization ratio, unit of microwave communication bandwidth used more and more in the system of multilevel much phase modulation method complex signal amplitude modulation )

扩频通信系统仿真 ——系统将基带信号(即信息)的频谱扩展至很宽的频带上,然后再进行传输,即将欲传输的信息数据用伪随机序列编码调制,实现频谱扩展,然后通过信道编码发送出去;接收端采用与发送端完全相同的伪随机序列作为本地解扩信号进行相关处理,以恢复信息,最后进行解调,完成整个系统的接收。(Simulation of spread spectrum communication system- the system baseband signal (ie, information) be extended to a wide spectrum of frequency bands, and then transferred, will want to use transmitted information data sequence of pseudo-random code modulation, to achieve expansion of the spectrum, and then sent channel coding receiver and transmitter use the same pseudo-random sequence as related to the local despreading signal processing, in order to restore the information, the final demodulation, the receiver to complete the system.)
