Analysis on Orthogonal-Code Repeat Transmission for MIMO-OFDM System
In this paper,we propose a repeat transmission scheme for MIMO-OFDM system.The data symbols are repeated in frequency and time domain by using orthogonfl codes.The performance of the proposed system with 8 transmit antennas and 2 receive antennas is evaluated by simulations and different repedtion schemes are employed for comparisons The results show that repeat transmission improves the performance of the MIMO-OFDM system for low-mobility scenarios.Besides，the zero-forcing receiver Can further improve the system performance.
