一种分布式MIMO信号的发射与检测方法
A transmission and detection technique for distributed MIMO signal
摘要
Abstract
Aiming at the problem of the asynchronous arrival at receiving antennas caused by the distributed location of transmit antennas, a transmission and detection technique is presented for distributed Multiple Input Multiple Output(MIMO) system with V-BLAST(Vertical Bell Labs Layered Space Time) architecture. In slowly fading channel, an equal diagonal upper triangular channel is constructed based on the Geometric Mean Decomposition(GMD) method by making use of the feedback channel state information to eliminate the imbalance among subchannel gains. The simulation results under Ricean fading conditions show that, compared with QR decomposition algorithm, the proposed detection technique can improve the BER performance remarkably.关键词
