Author Name : Renu Verma, Mangal Singh , Neelam Dewangan

Synopsis :

For high data rate communication, Orthogonal Frequency Division Multiplexing technique is most effective & it is widely used for various wireless communication for example Digital Video Broadcasting(DVB), Digital Audio Broadcasting (DAB), WiMAX etc. High Peak to Average Power ratio of an OFDM signal is the main drawback of this parallel transmission scheme. Several methods are available to reduce high PAPR of OFDM signal like Clipping, Tone Reservation, Tone Injection, Companding, Partial Transmit Sequence etc. Among these methods PTS is the most powerful method to reduce PAPR of OFDM. In this paper we describe the performance of partial transmit sequence technique applied to the OFDM signal to reduce PAPR, & shows the BER performance improvement after PAPR reduction .This paper also shows that the computational complexity is a drawback of PTS.
