Performance Analysis of Channel Estimation Algorithms
نویسنده
چکیده
Channel estimation plays an important role in wireless communication due to its random nature of the channel. Randomness creates the constructive or destructive fading. The combination of Orthogonal frequency-division multiplexing (OFDM) with multiple antennas at both the base station and mobile terminal converts frequency selectivity of the channel fading into flat fading parallel sub-channels. The performance can be improved by perfect channel estimations, used for non coherent detection. The paper compares different types of channel estimators and proposed a reduced complexity channel estimator. Keyword-MIMO, OFDM, fading, non coherent detection
