“…The main idea of PTS algorithm is dividing the input data into blocks, optimizing coefficient of each block, and last combining these blocks. In this way the PAPR value could be decreased [4].Fig. 1 shows the principle diagram of PTS method.…”

The fourth generation mobile communication system is a high-speed broadband wireless communication system, it needs MIMO and OFDM technology which have high spectral efficiency and suitable for a multi-path fading channel. Because the MIMO-OFDM system is still an multi-carrier modulation system, the main drawback is the high PAPR value. This paper proposed an improved algorithm based on optimized PTS to reduce PAPR in STBC MIMO-OFDM system. The simulation results show that the improved algorithm can effectively reduce the PAPR value and do not increase the amount of computation in STBC MIMO-OFDM system.
