A distortion-less technique which is generally used for peak to average power ratio (PAPR) reduction in OFDM system, selects a signal from many signals which are generated from different number of phases. This distortion-less technique is called as selective mapping (SLM). Selective mapping uses many phase sets for same information in order to minimize PAPR. Hence, it is an important task to design...
Selected Mapping (SLM) is the assuring peak to average power reduction (PAPR) technique for OFDM system. But this technique undergoes a very complex process for finding optimum phase sequence for the reduction of PAPR. Hence, in this paper highly optimized phases are derived and analyzed from proposed algorithm for selected mapping using several modulation schemes such as binary phase shift keying...
Orthogonal frequency division multiplexing (OFDM), also known as multi-carrier modulation scheme, is an attractive technology for upcoming communication system, to enhance data rate, higher spectral efficiency and better quality of service (QOS). In OFDM, first higher data stream has been divided into lower data streams and after modulation these data streams are together transmitted by orthogonal...
