多天线系统小区用户最佳预编码顺序的确定.介绍了一种在实际下行广播信道中采用脏纸编码（DPC）设计系统的方法，其 中基站发送端为多天线，接收端为单天线。主要的目标是在下行信道中满足每个用户的最小 速率要求和最大误码率要求的条件下最小化总体的传输功率(Cell users the best pre-coding sequence to determine a multi-antenna system. Describes an actual downlink broadcast channel using dirty paper coding (DPC) design system, wherein the multi-antenna base station transmit side, the receiving terminal as a single antenna. The main goal is to meet the conditions required by the minimum rate and maximum bit error rate of each user to minimize the overall transmission power in the downlink channel)
