Low-Complexity SQR-Based Decoding Algorithm for Quasi-Orthogonal Space-Time Block Codes
— In this paper, we propose a new decoding algorithm for quasi-orthogonal space-time block codes (QOSTBCs) which achieves near Maximum Likelihood (ML) performance while substanti...

Models of Complex Physical Systems Using Cell-DEVS
We present the definition of diverse models of physical systems using the Cell-DEVS paradigm. Cell-DEVS is an extension of the DEVS formalism that allows the definition of cellula...
