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 multiple-access interference (MAI). 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. Connection admission procedures are presented with related performance.
