Abstract :
In this paper, a new multicell OFDM blind power detection method is proposed. Relying on recent results of free deconvolution, our algorithm enables the terminal to count the number of surrounding base stations and to determine the power received from each of them, based on a limited number of snapshots. This is in sharp contrast with classical asymptotic blind techniques. A theoretical analysis is proposed to study the impact of frequency selectivity and the number of receive/transmit antennas. Simulations are provided to sustain the theoretical claims and are compared against classical techniques.
