A DECISION FEEDBACK LOOP USING PILOT BITS FOR CHANNEL ESTIMATION AND COMPENSATION OF CARRIER PHASE OFFSET

摘要

A decision feedback loop for a receiver for channel estimation and de-rotation of complex input symbols derived from a sampled information signal received via a channel which contains data organized into successive time slots, is configured to retrain and reinitialize the loop during each slot in order to mitigate slot to slot propagation of the estimation error.
