Comparative Study of a PAPR Reduction Techniques in MIMO OFDM System
Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) technology is one of the most useful technologies for Fourth Generation (4G) mobile radio communication. it effectively combats multipath fading, improves the bandwidth efficiency and increases the system capacity so as to provide reliable transmission. However, the main drawback in the MIMO-OFDM system is PAPR and offset sensitivity which results in restriction for practical applications. There are many methods for PAPR reduction such as coding, phase rotation, clipping. In this paper, the authors mainly investigate PAPR reduction methods i.e. PTS, SLM, clipping and filtering.
