Cooperative Base Station Coloring for Pair-Wise Multi-Cell Coordination

Base Station Association Game in Multi-cell Wireless Networks

We consider a multi-cell wireless network with a large number of users. Each user selfishly chooses the Base Station (BS) that gives it the best throughput (utility), and each BS allocates its resource by some simple scheduling policy. First we consider two cases: (1) BS allocates the same time to its users; (2) BS allocates the same throughput to its users. It turns out that, combined with use...

Cognitive Coordination for Cooperative Multi-Robot Teamwork

Behaviour Coordination for Cooperative Multi-Robot Systems

This report introduces a general formulation of relational behaviours for cooperative real robots and an example of its implementation using the pass between soccer robots of the Middle-Sized League of RoboCup. The framework supports explicit teamwork between two team mates. This implies that both participants know from each other that they are committed to the relational behaviour and that the...

Design of MIMO-OFDM multi-hop relaying with cooperative base station

Basically, in cellular network systems, the relay station (RS) is used to increase the cell coverage of mobile stations (MS) at a cell edge. But, the system performance due to the use of RS is interfered by the neighboring cells and decreased by the low power of received signals, generally. In order to overcome these disadvantages and get a diversity gain or a high data rate, we design and prop...

Asynchronous Interference Mitigation in Cooperative Base Station Systems

Cooperative transmission by base stations (BSs) can significantly improve the spectral efficiency of multiuser, multicell, multiple input multiple output (MIMO) systems. We show that contrary to what is often assumed in the literature, the multiuser interference in such systems is fundamentally asynchronous. Intuitively, perfect timing-advance mechanisms can be best only ensure that the desired...
