To Code or Not to Code Across Time: Space-Time Coding with Feedback
Abstract— Space-time codes leverage the availability of multiple antennas to enhance the reliability of communication over wireless channels. While space-time codes have initiall...

Bit Error Performance of Orthogonal Space-Time Block Codes over Time-Selective Channel
— Most of the existing works on space-time block codes (STBC) assume the channels are quasi-static, i.e., they remain invariant within one block. This assumption is not always tr...

Demodulation and Performance Analysis of Differential Unitary Space-Time Modulation in Time-Varying Rician Channels
Abstract— Studies on differential unitary space-time modulation are mostly focused on Rayleigh fading channels. In this paper we present new analytic results for the maximum-like...

Using Cell-DEVS for Modeling Complex Cell Spaces
Cell-DEVS is an extension to the DEVS formalism that allows the definition of cellular models. CD++ is a modeling and simulation tool that implements DEVS and Cell-DEVS formalisms....

Test-Time, Run-Time, and Simulation-Time Temporal Assertions in RSP
For cost-effective prototyping, system designers should have a clear understanding of the intended use of the prototype under development. This paper describes a classification of...
