Abstract
We propose an adaptive and parameter-independent per-survivor processing algorithm to improve the receiver performance on time-varying channels. With a variable step size for a plurality of survivor paths, this new method eliminates the dependency of all the survivor paths and improves the convergence rate of channel estimation.
