Abstract
Multiple Input Multiple output Orthogonal Frequency division Multiplexing (MIMO-OFDM) is a prepossessing modulation technique that have achieve notable heed in wireless environment nowadays. It improves the bandwidth efficiency and increases system capacity so as to provide a reliable transmission. However it has a high increase in PAPR (peak-to-average power ratio) due to the use of large number of sub carriers which result in many restrictions for practical applications. A novel hybrid approach is presented in this paper for the PAPR reduction by merging PTS and clipping together. This paper consists of various technique for reducing peak-to-average power ratio that are developed in last two decades such as PTS, clipping, CMA etc. The simulation result shows a collation between different PAPR reduction techniques. We propose and demonstrate an algorithm using two different techniques together and the results are verified using MATLAB software. We also comment on the computational complexity and practicability of these approaches.
