A Comparison of Time-Space Schemes for Graphical Models
We investigate three parameterized algorithmic schemes for graphical models that can accommodate trade-offs between time and space: 1) AND/OR Adaptive Caching (AOC(i)); 2) Variabl...

An Adaptive Frame-Based Interpolation Method of Channel Estimation for Space-Time Block Codes in Moderate Fading Channels
Abstract -- The application of Orthogonal SpaceTime Block Codes (O-STBC) as the encoding scheme in the presence of "non-quasi-static" fading was considered. A simple and ...

A Space- and Time-Continuous Model of Self-Organizing Robot Swarms for Design Support
— Designing and implementing artificial self-organizing systems is a challenging task since they typically behave nonintuitive and no theoretical foundations exist. Predicting a...

Golden Space-Time Block Coded Modulation
In a slow fading MIMO channel, we consider a coded modulation scheme where the inner code is the Golden Code. In this case, a lower bound for the minimum determinant is given by th...

New Space-Time Trellis Codes for Slow Fading Channels
— New space-time trellis codes with 4-PSK, 8-PSK and 16-QAM for two transmit antennas in slow fading channels are proposed in this paper. The codes are designed specifically to ...
