Abstract :
Recent results show that non-parametric linear receiver equipped with multiple receive antennas is an effective solution for ad hoc network under the imperfect channel state information at receiver (CSIR). In this paper, we propose an interference aware node activation strategy that efficiently controls the data transmission and back off based on the measured interference power. Our numerical results show that if optimization over the channel estimation threshold is provided, then the effective data rate of the proposed scheme is higher than that of the conventional channel estimation even under the system delay occurred.
