Data communication unit and method thereof for iterative decoding

摘要

A method (400) for receiving one or more data blocks in a data communication system comprises the step of receiving one or more data blocks at a receiving communication unit. The method further comprises the steps of determining (410) a-priori whether an iterative decoding operation of the one or more received data blocks is likely to converge; and requesting (420), by said receiving unit in response to determining that an iterative decoding operation is unlikely to converge, a re-transmission of said one or more data blocks. A communication unit and a communication system are also provided. <??>In this manner, the method prevents a receiver from performing wasteful (in a processing power and/or time sense) iterative decoding operations. Moreover, the overall delay in the receiver is also improved. <IMAGE>
