摘要

传统的代码获取技术不会利用所有可用信息来进行决策，而只使用其中的一部分。利用扩频码的统计特性，提出了一种最大后验概率(MAP)码采集方案，有效地利用了所有可用信息。计算机模拟结果表明，与传统方案相比，该方案的性能有了显著提高

Maximum a posteriori Probability (MAP) Code Acquisition in Multiuser DS/CDMA Systems

Conventional code acquisition techniques don't exploit the entire available information for decision making but only use a part of it. A maximum a posteriori probability (MAP) code acquisition scheme is proposed which efficiently utilizes all the available information by exploiting statistical properties of spreading codes. Computer simulations show significant performance improvements over conventional schemes
