Abstract
Channel state information is required for the coherent detection and decoding of turbo codes transmitted over flat-fading channels. A channel estimation technique suitable for turbo codes is presented. The technique uses pilot symbols to obtain initial channel estimates, and refines the estimates after each iteration of the turbo decoder
