摘要：Electronics communication system has revolutionized the face of the world. Communication with someone a mere century back was only possible by physical mode. But now that can be done just by clicking a switch on the telephone pad or by just a click of the mouse. Even live television report, live games telecast could not be possible without wireless communication. 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 communications. Signals, which were initially sent in the analog domain, are being sent more and more in the digital domain these days. For better transmission, even single carrier waves are being replaced by multi carriers. Multicarrier systems like CDMA and OFDM are nowadays being implemented commonly. OFDM system is vastly used in communication system, but there is major problem faces when implement the system is high peak to average power ratio of this system. There are number of techniques to deal with the problem of PAPR. Some of them are partial transmit sequence (PTS) and Complexity PTS. In this paper we have focused on learning the basics of an OFDM System and have undertaken various methods to reduce the PAPR in the system so that this system can be used more commonly and effectively
