چکیده

The Orthogonal Frequency Division Multiplexing is one of the widely used modulation techniques in the broadband wireless technology. One of the main problems is the high peak-to-average power ratio of transmitted signal due to the superposition of many subcarriers. This paper presents a new hybrid peak-to-average power ratio reduction technique, which combines a partial transmit sequence method with the clipping method. The paper highlights the performance and advantages of the mixed technique and compares it with other existing methods. The simulations shown that the proposed technique realizes an increased peak-to-average power ratio with a decreased signal distortion compared to clipping method. Keywords-OFDM; PAPR; Partial Transmit Sequence; Clipping
