摘要

MIMO结合OFDM提供高吞吐量和系统容量。MIMO OFDM从根本上提高了4G技术的频谱效率和系统可靠性。该系统提供高峰值平均功率比(PAPR)。为了降低高的PAPR，我们实现了一种加扰技术，即部分发送序列(PTS)。仿真结果表明，该算法具有较好的PAPR降低效果。

Design an efficient algorithm for peak to average power ratio reduction in STBC based MIMO-OFDM system

MIMO combined with OFDM provides high throughput and system capacity. MIMO OFDM radically improves spectrum efficiency and system reliability for 4G technology. The system offers high peak to average power ratio (PAPR). In order to reduce high PAPR, we implement one of the scrambling techniques namely Partial transmit sequence (PTS). The proposed algorithm provides better PAPR reduction which can be verified by simulation results.
