Blind collision resolution for mobile networks in fast-fading channels

Network-assisted diversity multiple access (NDMA) is a novel algorithm that resolves packet collisions deterministically by means of source separation techniques. The blind version of NDMA (B-NDMA) relies on the presence of a fading process that induces constant channel parameters over long slot times, as well as, the transmitter-receiver phase synchronization. In this paper, independent component analysis (ICA) is integrated into NDMA to provide blind collision resolution with high throughput/delay performance in a fast-fading channel environment and without phase control.
