The sphere decoding algorithm finds applications in multi-input multi-output (MIMO) decoding, because it achieves near maximum likelihood (ML) detection performance with significantly reduced computational complexity. Previous work has focused on implementations based on K-best or depth-first search, limiting the BER performance or the search speed. This paper presents a scalable multi-core sphere decoder architecture that can combine the advantages of the K-best and depth-first search methods… CONTINUE READING
