Abstract

This paper focuses on the competitively optimal power-control and signal-shaping for "ad-hoc" networks composed by Multiple-Antenna noncooperative transmit/receive terminals affected by spatially colored Multi-Access Interference (MAI). The target is the competitive maximization of the information throughput of each link active over the network. For this purpose, the MAI-impaired network is modeled as a noncooperative strategic game, and sufficient conditions for the existence and uniqueness of the Nash Equilibrium are provided. Specifically, the main contribution of this paper may be so summarized. First, we develop fully distributed and scalable power-control and signal-shaping algorithms allowing the implementation of asynchronous Space-Division Multiple Access Strategies (SDMACSs) able to guarantee the competitive maximization of the users' throughput under both Best Effort and Contracted QoS access policies. Second, we give evidence that the developed SDMACSs outperform (in terms of aggregate throughput) the conventional centralized ones (as TDMA/FDMA/CDMA), specially in operating scenarios affected by strong MAI. © 2005 IEEE.
