中文说明：对信号进行频谱分析及滤波，对HARQ系统的吞吐量分析，主要是基于mtlab的程序，详细画出了时域和频域的相关图，使用混沌与分形分析的例程，采用偏最小二乘法。
English Description：
The signal of frequency spectrum analysis and filtering, the HARQ system throughput analysis is mainly based on MTLAB procedures, detailed paintings out of the time domain and frequency domain correlation diagram, using chaotic and fractal analysis routines, using partial least squares method.
