A Multistack Algorithm for Soft MIMO Demodulation
Abstract
We propose a family of list-based soft demodulators for multiple-input–multiple-output (MIMO) communication systems based on a multistack algorithm for traversing the tree structure that is inherent in the MIMO demodulation problem. The existing stack algorithm for MIMO soft demodulation stores a single stack of visited nodes in the tree and expands the stack using the “best-first” principle. In the proposed multistack algorithm, the single …
