This function is used to forward link IS-95 system simulation, including the spreadspectrummodulation, matched filter, RAKE receiver, and other related communication module.
此函数用于IS-95前向链路系统的仿真，包括扩频调制，匹配滤波，RAKE接收等相关通信模块。

As a result, the computer simulations show that the LPI capability of the new DSSS modulation become more effective within the same bandwidth and SpreadSpectrum gain.
计算机仿真结果表明，在调制带宽或扩频增益不变的前提下，提高了DSSS调制信号的低概率截获性能。

Aiming at the spectrumspread problem of traditional digital modulation signals, a time-phase modulation (TPM) method with abrupt phase change characteristic is proposed.
