Abstract

In wireless communication orthogonal frequency division multiplexing (OFDM) is a special case of multicarrier transmission, where a single data stream is transmitted over a number of lower rate subcarriers. This new standard is the first one to use OFDM in packet-based communications, while the use of OFDM until now was limited to continuous transmission systems .Channel estimation is very important in order to get original information at receiver side. In paper the BER is calculated using Rayleigh fading channel using AWGN noise. It is going to be compared the BER by channel estimation methods like LS (Least square), DFT (Discrete Fourier Transform) for DFT-OFDM and DCT-OFDM. And it would be concluded that DFT based channel estimation is better than LS in both DFT-OFDM and DCT_OFDM. And also concluded that DCT-OFDM is better than DFT-OFDM for low range of SNR.

Key Words

DFT-OFDM, DCT-OFDM, pilot, channel estimation, LS, DFT.
