Method and apparatus for adaptive Turbo decoding of a plurality of radio channels performing CRC at the end of each iteration

摘要

the invention relates to an iterative method and a device (20) for decoding of data frames via a number of channels (a, b) the turbo coded empfangssignalen (21).the computing power of digital signal processors (dsps) as effectively as possible to profit, it is proposed that, starting from a first channel (a; b) the quality of the first channel (a; b) the decoded signal (33) after each iteration (a1, a5, b1,... ...b3) is checked, and at least another channel (b, a) is switched when a vorgebbare umschaltbedingung is given. the umschaltbedingung can). a vorgebbare quality of decoded signal assigned to the channel (33).to determine the quality of the decoded signal (33) is in particular a cyclic redundancy check (crc) after each iteration (a1,..., a5, b1,..., b5) is proposed.
