Design and Analysis of Enhanced Receivers for Wireless Personal Communications Networks

尽管通信在过去几十年中取得了巨大的进步，但今天绝大多数的个人通信仍然是通过有线系统进行的。然而，随着个人通信网络(PCN)和数字蜂窝通信时代的到来，越来越多的通信将是无线的，或者说是无缆的。PCN的一个主要考虑因素是多址技术，而扩频码分多址(CDMA)似乎是最好的选择。该研究针对码分多址环境，提出了一种改进的标准接收机设计，从而提高了系统性能。重新设计是基于变换域处理的信号处理技术，并将产生比传统相关接收器更接近最佳检测器的接收器。研究将包括分析和数值模拟。

Although there have been enormous advances in communications over the past several decades, the vast majority of personal communications today is still done through wired systems. However, with the coming of age of personal communications networks (PCN) and digital cellular communication, more and more communications will be wireless, or untethered in the future. A major consideration in PCN is the multiple accessing technique, and it appears that spread spectrum code division multiple access (CDMA) is the best choice. This research deals with the CDMA environment, and a modified design of the standard receiver that results in enhanced system performance is presented. The redesign is based around the signal processing technique of transform domain processing and will result in a receiver which more closely approximates an optimal detector than does the conventional correlation receiver. The research will involve analysis an numerical simulation.
