چکیده
Background: MIMO OFDM systems Performance has been analyzed, using A Peak to Average Power Ratio Reduction Technique by Threshold Detection .Objective: The performance of UWB channel models has been analyzed for MIMO OFDM systems. Results: OFDM symbols to effectively reduce the peak power for the MIMO OFDM system. Conclusion: In this paper, the performance of UWB channels is analyzed for MIMO OFDM systems. A Peak to Average Power Ratio Reduction Technique by Threshold Detection has been considered for different channel realizations. A new method is proposed to effectively reduce the peak power of OFDM symbols which can control a peak reduction signal level in each subcarrier by iterative signal processing. In the proposed method, the signals are adaptively clipping and threshold and the filtering to effectively remove out-of-band components without peak reduction effect is combined. The peak reduction effect of the proposed method was clarified by computer simulation.
