We utilize axiomatic bargaining theory to depict certain implications of continuity properties of resource allocation strategies in wireless systems. Feasible utility sets are characterized as sub-level sets of interference functions. The collective choice function is used to represent resource allocation strategies. We use an axiomatic framework to emulate certain desirable properties of resource...
Power management and energy-awareness has become popular in mobile computing as well as mobile communications. In future wireless communication systems, the energy efficiency of terminals and base stations has to be improved. Therefore, we propose a new utility function which is the difference of the capacity and a weighted power cost term. Next, the utility region for single-antenna and multi-antenna...
We consider the broadcast phase of a three-node network, where a relay node with multiple antennas establishes a bidirectional communication between the two other nodes each equipped with a single antenna using a spectrally efficient two phase protocol. In the first phase, both nodes transmit a message to the relay node, which decodes the messages. In the second phase the relay broadcasts a re-encoded...
The resource allocation problem in wireless systems with full cooperation will be characterized using collective choice functions and an axiomatic framework. The axiomatic framework will be used to characterize different properties of the operating point of resource allocation strategies (e.g. efficiency, robustness). A new axiom of comparability will be introduced and the conditions under which it...
Othogonal space-time block codes (OSTBC) are an efficient mean in order to exploit the diversity offered by the wireless multiple-input multiple-output (MIMO) channel. It was shown that the Alamouti scheme, an OSTBC for nT = 2 transmit antennas, achieves the capacity of such MIMO channels with nR = 1 receive antenna. However, by increasing the number of transmit antennas, the transmission rate of...
This paper, gives a general framework to investigate the existence and the general structure of causal inverse filters for multiple-input multiple-output (MIMO) systems with intersymbol interference (ISI). It gives necessary and sufficient conditions for the existence of causal and stable inverse filters allowing for further properties of the receive filters such as stability and smoothness of its...
