摘要

给出了一种对扩频信号进行编码的方法,使其在幅值和相位上都表现得像噪声。二进制PN生成器用于开发大量生成高斯码的代码。就信噪比而言,对于大扩频比,性能与典型的双相PSK调制或非扩频二进制通信系统渐近相同。

Spread Spectrum Amplitude/Phase Coding using Binary PN Generators
A means of coding a spread spectrum signal so that it appears noise-like in both amplitude and phase is given. Binary PN generators are used to develop the code which becomes Gaussian for a large number of generators. Performance, in terms of signal-to-noise ratio, is asymptotically the same as that of typical bi-phase PSK modulation, or unspread binary communications systems, for large spreading ratios.
