Performance Enhancement Technique for OFDM Using Channel Estimation Technique

Orthogonal Frequency Division Multiplexing (OFDM) has recently been applied in wireless communication systems due to its high data rate transmission capability with high bandwidth efficiency and its robustness to multi-path delay. Fading is the one of the major aspect which is considered in the receiver. To cancel the effect of fading, channel estimation and equalization procedure must be done at the receiver before data demodulation. Many channel estimation and equalization algorithms are studied in the literatures. This project mainly deals with pilot based channel estimation techniques for OFDM communication over frequency selective fading channels.
