Coding Schemes for User Cooperation in Low-Power Regimes
We consider the design of cooperation coding schemes for a two-user multi-access channel (MAC). In particular, we consider two block Markov coding schemes, namely, the multiplexed...

Cross-Layer Optimal Policies for Spatial Diversity Relaying in Mobile Ad Hoc Networks
In order to adapt to time-varying wireless channels, various channel-adaptive schemes have been proposed to exploit inherent spatial diversity in mobile/wireless ad hoc networks w...

Adaptive Modulation and Coding for Bit Interleaved Coded Multiple Beamforming
— Bit interleaved coded multiple beamforming (BICMB) was previously designed to achieve full spatial multiplexing of min(N, M) and full spatial diversity of NM for N transmit and...

Frequency-Domain Eigenbeam-SDM and Equalization for High Speed Data Transmissions
— In wireless communications, the channel consists of many resolvable paths with different time delays, resulting in a severely frequency-selective fading channel. The frequencyd...

Hierarchically organised evolution strategies on the parabolic ridge
Organising evolution strategies hierarchically has been proposed as a means for adapting strategy parameters such as step lengths. Experimental research has shown that on ridge fu...
