项目摘要

North State University Alexandra Duel-Hallen RIA: Multiuser Detectors and Equalizers for Present and Future Wireless Networks The objective of this research is to increase the capacity of wireless communications systems by providing simple and reliable detection algorithms. The research is a multi-pronged effort in the area of detection for wireless communication networks. The first direction addresses multiuser receivers for Code-Division Multiple Access (CDMA) systems. These low complexity adaptive multiuser detectors for CDMA systems are expected to operate reliably in the presence of strong interferers. Incorporation of the proposed receivers into CDMA systems should lead to significant capacity improvements for the future generation of wireless networks. The second direction is diversity reception for multipath fading channels. The methods studied are expected to alleviate the shortcomings of the existing frequency diversity receivers and improve the reliability of wireless communications by resolving multipath present in the mobile environment. The focus of the third component of the research is adaptive equalization for present digital mobile radio systems. The thrust will be to find receivers that are less complex and more reliable than those currently sued. The final direction is the investigation of capacity improvement of packet radio or local area networks using joint demodulation.

北州立大学Alexandra Duel-Hallen RIA：当前和未来无线网络的多用户检测器和均衡器本研究的目的是通过提供简单可靠的检测算法来增加无线通信系统的容量。该研究是无线通信网络检测领域多管齐下的努力。第一个方向针对码分多址（CDMA）系统的多用户接收机。这些用于CDMA系统的低复杂度自适应多用户检测器有望在存在强干扰的情况下可靠地工作。将所建议的接收器并入CDMA系统应导致未来一代无线网络的显著容量改进。第二个方向是多径衰落信道的分集接收。所研究的方法有望通过解决移动环境中存在的多径问题，缓解现有频率分集接收机的不足，提高无线通信的可靠性。第三部分的研究重点是现有数字移动无线电系统的自适应均衡。重点将是找到比目前起诉的接收器更简单、更可靠的接收器。最后的研究方向是利用联合解调技术提高分组无线或局域网的容量。
