AbstractMIMO-OFDM is a key technology being widely used these days for 4 G communication systems but its main drawback is high PAPR. Selected mapping is commonly used approach for PAPR reduction but in SLM there is requirement of side information (SI) to be sent along with the input data signal and leading to the loss in data rate and increased complexity. In this article, we have come up with a technique for PAPR reduction in which there is no requirement of transmission of side information and therefore preserves the data rate and also provides sufficient reduction in the PAPR. In this technique, SI embedding is performed in the form of subcarrier location (index) by increasing its power. The simulation results demonstrate that the scheme which has been proposed provides the favorable response in terms of bit error rate (BER), PAPR reduction and SI detection capability.
