Abstract The main problem of decoding Turbo TAST code is to reduce its dimension. Performance of different reduction methods varies greatly. Null space method is no longer valid for TAST code. Reduction to single input single output with MMSE equalization achieves a good balance between the performance and computational complexity. Link level capacity is deduced for these methods, and it agrees well with the results of simulation.
