Improved mobile telephone universal mobile telecommunications system receiver having digital demodulator with iterative digital decoding and feedback loop with test means iteration dependent code input quality.

摘要

The receiver (2) has a digital demodulator (23) and iterative decoding across a feedback loop of coded sequences. The feedback loop has a test means (26) comparing each iteration of a coded sequence of a code with cyclic redundancy, extracting a corrected sequence entering in the loop a code with cyclic redundancy determined as a function of the elements of the corrected sequence entering, stopping the sequences when the two codes compared are identical.
