PAPR Reduction in MIMO OFDM System Using ZCT Technique
Roshni Gulwani | Ekant Sharma
Abstract: An Arrangement of using OFDM system with space time block coded - multiple input multiple output (STBC-MIMO) System provides excellent performance against Multi-path effects and frequency selective fading. However, one of the major drawback of MIMO-OFDM have high peak-to-average power ratio (PAPR) in order to the signals transmittted on different antennas. In this paper, we propose Zadoff-Chu matrix Transform (ZCT) technique to reduce the peak-to-average power ratio (PAPR) with precoding and postcoding Alamouti STBC MIMO-OFDM system. To reduce the high PAPR, BPSK modulation techniques is used for different values of N (64, 128, 256). Our proposed work shows that ZCT POSTCODED based STBC MIMO-OFDM SYSTEM has the lowest PAPR performance compared to ZCT PRECODED based STBC MIMO-OFDM SYSTEM. MATLAB simulation shows that the performance of the proposed algorithm significantly improves the PAPR reduction.
