Abstract

Orthogonal Frequency Division Multiplexing (OFDM) provides an attractive solution to high rate wireless communication which provides robustness to interference and multipath fading. Large peak to average power ratio (PAPR) is one of the greatest challenges in multicarrier communication. This paper proposes a comparatively simple, low noise technique for transmission of a multicarrier signal in high rate wireless communication. Clipping based active constellation is one of the commonly used techniques for reducing large peaks. But this technique results in peak regrowth, which degrades the bit error rate (BER) performance and increase in in-band noise and out-of band noise. This paper proposes a technique that reduces computational complexity and gives better performance with respect to Bit-error-rate. The improvement on BER performance is studied for various compression profiles. The proposed method effectively reduces nonlinear distortion and BER resulting in low noise system. This simplifies design of transmitter and receiver. The simulation results show that the proposed technique results in lower PAPR and gives simple solution.

Keywords: Orthogonal Frequency Division Multiplexing(OFDM), Exponential Companding, Peak to Average power ratio(PAPR), Bit Error Rate (BER).
