A novel channel estimator for turbo decoding in stationary and non-stationary flat fading channel
A new and efficient fast Fourier transform (FFT) channel estimation filter with an integrated fading rate calculator is developed for turbo decoding in a flat fading channel. It removes the need for a-priori knowledge of the channel fading rate for good performance which is a key requirement in many filters in the existing literatures. Under both time-invariant and time-varying fading rate, it achieves BER performance close to the optimum Wiener filter with a lower computational count
