PAPR reduction in OFDM system by using hadamard transform in BSLM techniques

Abstract

In this paper we use Hadamard transform in selective mapping (SLM) to reduce PAPR in OFDM systems. this technique could reduce more PAPR than ideal SLM and there is no need to transmit side information to receiver for recovering original data. It is shown that in some situations proposed technique improves the bit error rate (BER) and also has error correction property.
