Abstract: In this article an analysis on different PAPR minimizing schemes for MIMO-OFDM based wireless communication systems like clipping, selective mapping (SLM) and Partial Transmit Sequence (PTS) are presented. Several properties of OFDM maintain an appealing modulation scheme to support huge data rates in MIMO-OFDM based transmission used in wireless communication system. Apart from several advantages one principle drawback of the OFDM system is it produces huge values of PAPR. The PAPR can be minimized using few schemes like clipping, coding, peak windowing and tone reservation. Simulation results can give the examination between the different PAPR reduction techniques and can give the scope for analyze the different techniques based on different parameters like CCDF values and BER performance with respect to the variation in number sub carriers used for transmission However, huge number of these plans are not able to give a huge degradation in the PAPR by a low computational complexity, but the SLM technique provides essentially better attainment than the other schemes for MIMO-OFDM systems.
Keywords: CCDF, MIMO-OFDM and PAPR.
