Real-Time Performance Evaluation of a Receive Antenna Selection for MIMO-OFDM System

This paper describes a real-time performance evaluation of a receive antenna selection method for a spatial multiplexing multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system in a real environment. In this real-time performance evaluation, we employed a receive antenna selection method to select a suitable set of polarization antennas at the receiver side of the MIMO-OFDM system with low computational complexity. The receiver of the MIMO-OFDM system caught the preambles of the signal bursts to calculate the channel impulse responses and used them in calculating a cost function to decide a suitable set of polarization antennas. The results showed that the MIMO- OFDM system with the receive antenna selection method selected suitable sets of polarization antennas and achieved good performance.
