A new generic maximum-likelihood metric expression for space-time block codes with applications to decoding
… a simple low-complexity maximum-likelihood (ML) decoding algorithm. However, OSTBCs are limited in their error performance. This has led to the development of more general linear space-time block codes, such as quasi-orthogonal space-time block codes (QOSTBCs). QOSTBCs offer better error …

Multi-layered Space Frequency Time Codes
… (MIMO) systems. The first studies and compares decoding algorithms for multi-layered space time coded (MLSTC) systems. These are single user systems that combine spatial multiplexing and transmit diversity. Each layer consists of a space time code. The detection algorithms are based on …

MIMO communications over multi-mode optical fibers
… well as wireless communications. We show that a sphere decoding (SD)-like approach can be used to reduce the computational complexity of the vector Viterbi algorithm (VVA), an extension to the Viterbi algorithm for MIMO systems. Our combined SD-VVA approach is attractive because it provides …

Digital communication receiver algorithms and architectures for reduced complexity and high throughput
… computationally efficient detection and decoding algorithms in the receiver. Hence, it is crucial to develop receiver algorithms that can offer good performance-complexity trade-offs in high dimensional communication systems such as multi-input multi-output (MIMO) systems and systems with …
