Performance Analysis of PAPR Reduction in MIMO OFDM System Using Modified Constant Modulus Algorithm

S. Sujitha, R. Ramachandran

A rapid increase in the demand of high speed data communication access leads to the development of exciting technology named MIMO OFDM. MIMO OFDM technology is one of the 4G communication standards. Though it has many merits, it still suffers from high peak to average power ratio problem. Many techniques were introduced to solve this problem. This paper presents an excellent solution to tackle this high PAPR problem using modified constant modulus algorithm (MCMA). Simulation is done using MATLAB Simulation Package. The obtained simulation results show that the PAPR Reduction performance of MCMA is better than that of Scrambling Schemes.
