The process of joint user and receive antenna scheduling is very vital in the uplink direction of multi-antenna wireless data communications system with multiple users. With higher number of receive antennas and active users, the search space becomes huge for the joint user and receive antenna scheduling process. It is very difficult to accomplish the searching through the entire search space within the wireless communication time frame. In this paper, low complexity based methods for joint scheduling of users and receive antennas have been proposed. Here, this has been shown that low complexity based scheduling scheme is able to attain system throughput which is quiet close to that of exhaustive search algorithm (by searching the entire search space). Moreover, an interesting observation can be made that the number of complex multiplications and additions required by these low complexity methods is quite less than that of exhaustive search algorithm.

用户和接收天线的联合调度过程在具有多个用户的多天线无线数据通信系统的上行链路方向上至关重要。随着接收天线和活跃用户数量的增加，联合用户和接收天线调度过程的搜索空间变得巨大。在无线通信时间范围内在整个搜索空间中完成搜索非常困难。本文提出了一种基于低复杂度的用户和接收天线联合调度方法。在这里，这表明基于低复杂度的调度方案能够获得系统吞吐量，该吞吐量接近穷举搜索算法（通过搜索整个搜索空间）。此外，
