ABSTRACT

The main purpose of this research is to estimate channel and also track channel so that at the receiver a noise free signal can be obtained. OFDM is a multicarrier technique in which the transition of data will be done by dividing the stream into multiple parallel bit streams and a then the signals are modulated with sub-carriers. By this the complexity of the receivers will be very high. To optimize the receiver, channel estimation and channel tracking will be helpful. In channel estimation the pilot tones are introduced into all subcarriers at transmitter which will...
