Abstract:
Error free transmission is one of the main aims in wireless communications. With the increase in multimedia application, large amount of data is being transmitted over wireless communications. Due to the channel fading and the Doppler shifts caused by user mobility, a common problem in wireless systems, additional technologies are needed to combat multipath propagation fading and Doppler shifts. Time-variant channel estimation is one such crucial technique used to improve the performance of the modern wireless systems with Doppler spread and multipath spread. Channel estimation is done by estimating the time-varying channel frequency response for the OFDM symbols. . The Least Square (LS) method is used for channel estimation technique using the block type pilot sequences. Time-variant channel estimation using pilot Sequences technique is a useful channel estimation technique in mobile wireless communication for accurately estimating transmitted information. The main advantage of pilot sequence is allowing more accurate representation of high mobility mobile wireless channels with low complexity. The main goal is to test the recently proposed method, time-variant channel estimation using pilot sequence.
