Hey GNU Radio'ers! Another week has passed. Thus, it's time for my next project update. The week started with a fairly good event. I found a bug in the decoder which led to incorrect results. I studied various papers and algorithms for decoding performance improvements. Especially Successive Cancellation List Decoding SCLD caught my attention. Also, papers exist which describe vector optimization for x86 CPUs and SIMD utilization. I will get back to this once I'm working on VOLK optimization later in the project. In order to have meaningful codes available, I started working on some channel construction code. First of all, BEC channels can be calculated efficiently, but I don't consider them to be interesting for GNU Radio. Let me know if you have a different opinion on this. And why. I consider BSC as the most interesting case. There exist algorithms which approximate Z-parameters or channel capacities quite well. Also, Monte-Carlo simulations yield usable results. I'll stick with them for now and will work on more sophisticated algorithms later. Just as outlined in my timeline.
Next week will bring some C++ coding. Encoders and decoders are waiting to be implemented in C++ for FECAPI. More info and current project progress can be found in [1] and [2].
