The ever increasing demand for high data rate communication, and the use of radio resource management techniques requiring frame-by-frame adaptive coding/modulation to match user demands and channel conditions, pose a number of crucial problems to the design of versatile, high-speed iterative decoders, for both turbo-like and low-density parity-check codes.

Abstract
The ever increasing demand for high data rate communication, and the use of radio resource management techniques requiring frame-by-frame adaptive coding/modulation to match user demands and channel conditions, pose a number of crucial problems to the design of versatile, high-speed iterative decoders, for both turbo-like and low-density parity-check codes. Among them, we mention: The modification of the Soft-Input Soft-Output (SISO) algorithm in away that permits its implementation using several parallel processors working independently on segments of the received frame. The collisions in the process of reading/writing into/from the memory by the parallel processors. The design of prunable interleavers covering a wide range of information and/or code words lengths while keeping good spreading properties. The design of codes yielding awide range of code rates with good performance for the range of probability of error of interest.Pubblicazioni consigliate
