Modified Multiple Sub-blocking PTS Technique for Reduction in PAPR in OFDM System
Abstract: OFDM (Orthogonal frequency division multiplexing) is a multi-carrier modulation technique which provides better bandwidth efficiency at high data rate but the problem is it increases the PAPR. This increase in PAPR leads to loss of signal and in order rectify it cost of amplifiers has to be increased. Therefore, peak-to-average power reduction (PAPR) reduction is an important issue which is required to be solved. PAPR can be reduced by using …
