Fast Optimal Decoding of Multiplexed Orthogonal Designs by Conditional Optimization
IEEE Transactions on Information Theory
This paper focuses on conditional optimization as a decoding primitive for high rate space-time codes that are obtained by multiplexing in the spatial and code domains. The approach is a crystallization of the work of Hottinen et al. which applies to space-time codes that are assisted by quasi-orthogonality. It is independent of implementation and is more general in that it can be applied to space-time codes such as the Golden Code and perfect space-time block codes, that are not assisted bydoi:10.1109/tit.2009.2039069 fatcat:z7zotzbrvfcu7b3alzmoytztb4
