Blind channel estimation for Multiple-Input Multiple-Output system using Constant Modulus Algorithm

摘要: Display Omitted The channel length is blindly estimated and the impulse response determined.The cost function specifies signal noise level.Equalizer updates its tap weights based on of proposed CMA.With 4 taps, CMA achieves a faster convergence rate.The exhibit better MSE reduced error rate than other techniques. Multiple-Input Multiple-Output system plays major role in fourth generation wireless systems to provide high data rates. In this paper, blind estimation approach has been for finding signals received from MIMO (Multiple-Input Multiple-Output) transceiver. resultant information utilized system. used adaptation equalizer weights, Constant Modulus Algorithm which fading multipath propagation resulting Inter Symbol Interference. performance analyzed terms Mean Square Error Rate various Signal Noise Ratio.
