GFSK调制 脉冲成型滤波器为BT=0.3的高斯脉冲成型滤波器-GFSK modulation, pulse shaping filter of BT = 0.3 Gaussian pulse shaping filter

时变系统的频谱扩展，（信道是平坦的）仿真结果为：滤波后高斯过程的功率谱密度和由滤波器产生的相关高斯序列的时域值-Time-varying system, spread spectrum, (the channel is flat) simulation results as follows: the filtered Gaussian process power spectral density and produced by the filter related to the value of

本程序是 扩展高斯（EGF）滤波器 当两个输入为根号1/2的时候就是IOTA滤波器，用于通信系统发端的波形塑形-This function calculates a filter with egf characteristic

主要包括升余弦脉冲滤波器、平方根升余弦滤波器、 高斯滤波器(It mainly consists of raised cosine pulse filter, square root raised cosine filter and Gauss filter)
