Divya Rao, Sanjeev Ghosh . Performance Evaluation and Comparison of Various Channel Estimation Algorithms. International Conference and Workshop on Emerging Trends in Technology. ICWET, 3 (None 2011), 7-10.
This paper compares different channel estimation techniques used in OFDM. In order to exploit all these advantages and maximize the performance of OFDM systems, Channel state information (CSI) plays a very important role. Due to the multipath channel there is some intersymbol interference (ISI) in the received signal.Therefore a signal detector (like MLSE or MAP) needs to know channel impulse response (CIR) characteristics to ensure successful equalisation (removal of ISI).The Mean Squared Error and Signal-to-Noise Ratio (SNR) is used as a metric for comparing the results. The Simulation is done and comparison is shown using the simulation plots.
