Investigation of PAPR Reduction in MIMO-OFDM System using PTS and SLM Techniques

Maan Singh, Vijay Kumar


Abstract: Communication is one of the important aspects of life. With the advancement in age and its growing demands, there has been rapid growth in the field of communication. In recent years, the communication industry has started focusing on fourth generation (4G) mobile communication systems. It is expected that 4G will provide a comprehensive and secure IP solution where voice, data, and multimedia can be offered to users at anytime, anywhere with higher data rates than previous generations. For better spectrum efficiency and obtains as high as 100Mbps wireless transmission rate, 4G requires more advanced communication techniques to be employed. Multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM) have, therefore, been adopted due to their superior performance. OFDM is an attractive modulation technique for transmitting large amount of digital data over radio waves. However, the principal drawback of OFDM is that the peak transmitted power can be substantially larger than the average power; abbreviated as PAPR. It is preferred to have a minimum PAPR, as it will allow a higher average power to be transmitted for a fixed peak power; and thus, improving the overall signal to noise ratio at the receiver. Therefore, this paper investigates of significant reduction in PAPR has been achieved using selected mapping (SLM) and partial transmit sequence (PTS) in MIMO-OFDM systems. From the analysis, it is inferred that PTS method provides a better PAPR reduction performance compared to SLM method.
