A Scalable VLSI Architecture for Soft-Input Soft-Output Single Tree-Search Sphere Decoding

Multiple-input multiple-output (MIMO) wireless transmission imposes huge challenges on the design of efficient hardware architectures for iterative receivers. A major challenge is soft-input soft-output (SISO) MIMO demapping, often approached by sphere decoding (SD). In this brief, we introduce-to o...
