Abstract

Soft decision, i.e. probability based, decoding (70) is applied to a format identifier field, in particular to a transport format combination indicator (TFCI) field of a data signal in a noisy channel, particularly for digital data communication and 3G portable telephony. The described soft decision decodings (70) are applicable to various forms of block codes and trellis codes.
