Abstract
A radio telecommunications receiver operates to receive digital data symbols or bits by iterative determination of soft estimates of symbols or bits followed by a hard decision as to what symbol or bit was intended. The receiver comprises a first processor operative to provide first soft estimates of symbols or bits of the received signal and a second processor operative to decode the first soft estimates and to provide second soft estimates of the symbols or bits. The receiver also comprises a combiner operative to provide third soft estimates back to the first processor for subsequent further decoding, the third soft estimates of each symbol or bit being dependent upon the respective second soft estimate and a respective previous second soft estimate.
