摘要
Abstract
With the miniaturization trend of equipment,the space between antennas is limited,thus the chan-nels are correlated. Suppose the transmitter is in high speed moving,the full channel state information( CSI) is unavailable,the beamforming( BF) design is based on the partial CSI. For a dual-hop fixed-gain amplify and forward( AF) relay network,where the source and destination are each equipped with multiple antennas, the optimal BF weights are designed to maximize the received signal-to-noise ratio( SNR) based on the par-tial CSI and then the outage probability( OP) and average symbol error rate( ASER) in a closed-form are de-rived. Simulations demonstrate the correctness of performance analysis and superiority of the proposed scheme. When ASER=10-2 and correlation coefficient=0. 8,1. 6 dB SNR is saved with the proposed scheme.关键词
