Performance evaluation of conventional and wavelet based OFDM system

Authors: Mahesh Kumar Gupta, S. Tiwari

Abstract:
In this paper we have compared the bit error rate (BER) performance and power spectral density of Discrete Fourier Transform (DFT) based OFDM system with wavelet based OFDM system. We also compared the performance of Least Square (LS) and Linear Minimum Mean Square Error (LMMSE) channel estimation technique for wavelet based OFDM system as well as DFT based OFDM system.

Keywords:
