摘要

在SDMA移动无线电系统上行链路上,有K>1个用户在同一频带和时隙进行传输。这些信号由一组M/spl /K天线在基站接收。提出了一种完整的基站接收结构,用于联合检测K个用户传输的比特。为了保证接收机的良好性能,提出了一种对doa敏感的信道分配方案。在实际模拟的三维移动无线电信道中进行了大量的仿真,证明了该概念的可行性。

Data detection and channel allocation on the uplink of an SDMA mobile radio system
On the uplink of an SDMA mobile radio system K>1 users are transmitting in the same frequency band and time slot. These signals are received at the base station with an array of M/spl ges/K antennas. A complete base station receiver structure to jointly detect the bits transmitted by the K users is presented. To guarantee a good receiver performance a DOA-sensitive channel allocation scheme is described. The feasibility of the concept is proved by extensive simulations in realistically modelled 3D mobile radio channels.
