Abstract |
|
Orthogonal Frequency Division Multiplexing (OFDM) is one of the prominent multicarrier modulation technique used for high speed data transmission in communication system. The PAPR problem is one of the most important issues for OFDM transmission systems. PTS and SLM are two very common schemes use for the PAPR reduction. PTS technique has higher computational complexity due to phase optimization. Some techniques have been proposed earlier for the reduction in the complexity by the use of new phase sequence. In this article we have proposed new SLM methods based on the use of new phase sequence and clipping to get reduction in complexity with reduced PAPR. |
