Mobile Channel Estimation Using M-SMFTF Adaptive Algorithm
In this research paper an adaptive algorithm M-SMFTF is used for mobile channel estimation with fast
convergence and low complexity. A multi-ray Jakes mobile channel model with a Doppler frequency shift is used in the
simulation. It is derived from SMFTF algorithm in which adaption gain is obtained only from forward predictors and new
likelihood variables. Complexity of M-SMFTF is reduced from 7L to 6L, where L is the filter length. It is used in different
problems like channel estimation and echo cancellation due to less complexity, high convergence speed and stability in the
presence of non stationary input signals.
