Abstract

It is well known fact that high PAPR value degrades the performance of OFDM system. In this paper, PTS (Partial transmit sequence) based approach is opted for the reduction of PAPR and three major contributions are made to the traditional PTS scheme. First, the phase sequence that is to be multiplied is changed, second the system is extended with hybrid mechanism of SLM (selective mapping) and PTS scheme in which additional hybrid scheme is opted. Third the benefits of DHT (Discrete Hartley transform) are incorporated with this system. It is found from the experimental results that the proposed MSD (modified sequence DHT) based system able to decreases the PAPR at a considerate factor and also able to preserve the OBI (out of band interference).
