Abstract

Orthogonal frequency division multiplexing is very well known technique for high speed data transmission in wireless communication. But the main disadvantage of using the OFDM system is high PAPR. This paper proposes to reduce PAPR using Huffman coding and IDWT. A simulation result shows that using Huffman coding combined with IDWT reduces PAPR about 11dB. Also we have tested the OFDM system for various sub-carriers.
