| 摘 要： | 本介绍利用声表面波（ＳＡＷ）固定抽头相位编码器制作的Ｒａｋｅ接收机，对于通过频率选择性慢衰落信道后的正交扩频信号，实现了分集合并。由于利用了匹配滤波器和正交扩频信号的性质，大大简化了接收机复杂性，并且对不同类型的时延扩散具有较强的适应能力。

| Abstract: | The Rake receiver using SAW fixed tap phase encoder is introduced.For the orthogonal spread spectrum signal through a frequency-selective slow fading channel,a renovated quasiequal-gain diversity combining is proposed and analyzed.This new method greatly reduces complexity and the enhancement of the flexibility to continuous or discrete time dispersion.This leads to the way for the implemention of Rake in mobile communicaiton. |
