Abstract EN

The channel capacity of MIMO system increases as a function of antenna pairs between transmitter and receiver but it suffers from multiple expensive RF chains.

To reduce cost of RF chains, antenna selection (AS) method can offer a good tradeoff between expense and performance.

For a transmitting AS system, channel state information (CSI) feedback is required to choose the best subset of available antennas.

However, the delay and error in feedback channel are the most dominant factors to degrade performances.

In this paper, the concept of AS method using reciprocal CSI instead of feedback channel is proposed.

The capacity performance of proposed system is investigated by own developing Testbed.

The obtained results indicate that the reciprocity technique offers a capacity close to a system with perfect CSI and gains a higher capacity than a system without AS method.

This benefit is from 0.9 to 2.2 bps/Hz at SNR 10 dB.
