Packet separation in wireless ad-hoc networks by known modulus algorithms

We consider an asynchronous ad-hoc network with multiple users transmitting packets at the same time. The signal of interest is modulated by a known amplitude variation. This allows the corresponding multichannel receiver to estimate the beam former weights that will suppress the interfering sources. We introduce “known modulus algorithms” (KMAs) to achieve this, and illustrate the, throughput improvements that can be expected.
