This paper presents implementation of a soft decision Viterbi decoder suitable for convolution codes with short constraint lengths. The decoder is based on a property of Viterbi algorithm that states “if the survivor paths from all possible states at time n are traced back then with high probability all the paths merge at time n-L where L is the survivor path length”. Pipeline structures are in...

This paper proposes the architecture of partial sum generator for constituent codes based polar code decoder. Constituent codes based polar code decoder has the advantage of low latency. However, no purposefully designed partial sum generator design exists that can yield desired timing for the decoder. We first derive the mathematical presentation with the partial sums set βc which is correspon...

This paper investigates an end-to-end neural diarization (EEND) method for unknown number of speakers. In contrast to the conventional cascaded approach speaker diarization, EEND methods are better in terms overlap handling. However, still has a disadvantage that it cannot deal with flexible To remedy this problem, we introduce encoder-decoder-based attractor calculation module (EDA) EEND. Once...
