北州立大学Alexandra Duel-Hallen RIA：用于现在和未来无线网络的多用户检测器和均衡器这项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。这项研究是无线通信网络检测领域的一项多管齐下的努力。第一个方向用于码分多址(CDMA)系统的多用户接收机。这些用于码分多址系统的低复杂度自适应多用户检测器有望在强干扰下可靠地工作。将拟议的接收器并入码分多址系统应该会为未来一代无线网络带来显著的容量改进。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，改善现有频率分集接收机的缺点，提高无线通信的可靠性。第三部分研究的重点是针对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被起诉的接收器更简单、更可靠的接收器。最后的方向是研究利用联合解调提高分组无线电或局域网的容量。

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.
