WebSphere Decoding A Matlab/Octave implementation of the eight Sphere Decoding algorithms outlined by A. Ghasemmehdi and E. Agrell, 2011 ("Faster Recursions in Sphere Decoding," IEEE Trans. Inf. Theory, vol. 57, no. 6, pp. 3530-3536). Usage All algorithms take a lower triangular generator matrix G or G ^-1 and a vector y as input. WebMay 16, 2015 · Abstract. In order to reduce the complexity of hard-output K-best decoding algorithm in multiple-input multiple-output (MIMO) systems and guarantee performance of the system, we propose a bit-sort (BS) strategy based on bit counting operation in hardware implementation for the K-best decoder. The proposed BS K-best algorithm finds out the ...
