Multiple packet reception in asynchronous wireless networks

Abstract

In this paper we present a scheme for multiple-packet reception (MPR) that allows the concurrent packet transmission from several asynchronous users and is based on a new algorithm for successive interference cancellation (SIC). Transmitted signals are superimposed at the destination nodes and also at a relay node. The system model allows for the transmitted packets to be superimposed asynchronously with an arbitrary pattern at each node that receives them. For the final version of the proposed scheme we present a joint MPR and channel decoding algorithm. © 2013 IEEE.
