  Abstract

Multi-input-multi-output (MIMO) systems are considered to improve the capacity and reliability of next generation mobile communication. However, the multiple RF chains associated with multiple antennas are costly in terms of size, power and hardware. Antenna selection is a low-cost low-complexity alternative to capture many of the advantages of MIMO systems. We proposed new joint Tx/Rx antenna selection algorithm with low complexity. The proposed algorithm is a method selects LR×LTchannel matrix out of MR×MT entire channel gain matrix where LR×LT matrix selects alternate Tx antenna with Rx antenna which have the largest channel gain to maximize Frobenius norm. The feature of this algorithm is very low complexity compare with Exhaustive search which have optimum capacity. In case of 4×4 antennas selection out of 8×8 antennas, the capacity decreases 0.5~2㏈ but the complexity also decreases about 1/10,000 than optimum exhaustive search.
