Analyze the time and space complexity of your solution. Compare your solution to others and identify areas for improvement.

We propose a simple optimal soft-input/soft-output symbol decoding algorithm for linear block codes which requires one forward recursion using a trellis. For many codes the decoding complexity is ...

Current proposals use the up*/down* routing algorithm to remove cyclic dependencies between channels and avoid deadlock. However, routing is considerably restricted and most messages must follow ...
