Optimal Coding Strategies for Bidirectional Broadcast Channels Under Channel Uncertainty
Bidirectional relaying is a promising approach to improve the performance in wireless networks such as sensor, ad-hoc, and even cellular systems. Bidirectional relaying applies to...

A Unified MIMO Architecture Subsuming Space Shift Keying, OSTBC, BLAST and LDC
In this paper, motivated by the recent concept of Spatial Modulation (SM), we propose a novel Generalized Space-Time Shift Keying (G-STSK) architecture, which acts as a unified Mul...

Measurement-based replanning of cell capacities in GSM networks
Due to the scarcity of the spectral resources and mobility of the portables, the call attempts may be blocked during call initiation or terminated during the hand-off process. Whe...
