Abstract
A cognitive coexistence radio utilizes message fractionation and physical layer channel assignment to achieve co-existence communications in the presence of interferers. A transmit signal is split into a plurality of streams for transmission in occupied channels according to power allocation and modulation scheme. A near-optimal selfish power allocation scheme is based on the water-filling solution. A receiver can receive and decode the streams using parallel MUDs.
