Choir Codes: Coding for Full Duplex Interference Management
Communication networks conventionally operate with half-duplex methods and interference avoiding schemes to manage multiple transceivers. Here, the authors consider a method in which nodes transmit and receive in concert to achieve full duplex communication without transmitter coordination. They build on a recent framework for full-duplex communication in ad-hoc wireless networks recently proposed by Zhang, Luo and Guo. An individual node in the wireless network either transmits or it listens to transmissions from other nodes but it cannot do both at the same time. There might be as many nodes as there are MAC addresses but they assume that only a small subset of nodes contribute to the superposition received at any given node in the network.
