Claim

1. An arrangement comprising:', 'a plurality of receiving antennas;', 'a MAP space-time decoder coupled to said plurality of antennas; and', 'a turbo decoder responsive to signals developed by said MAP space-time decoder.

2. The arrangement of claim 1 further comprising a plurality of at least two antennas responsive to output signals of said space-time encoder.

3. The arrangement of claim 1 where said turbo encoder is a turbo trellis coded modulation encoder.

4. An arrangement comprising:', 'a plurality of receiving antennas;', 'a MAP space-time decoder coupled to said plurality of antennas; and', 'a turbo decoder responsive to signals developed by said MAP space-time decoder.

5. The arrangement of claim 4 where said MAP space-time decoder evaluates probability measures.

6. The arrangement of claim 4 where said turbo decoder operates in accordance with a recursive method with two MAP processors providing information to each other.']
