Abstract

An algorithm for the recovery of multiple packets is proposed in this paper. The algorithm exploits the fact that every transmitter sends an implicit training sequence along with the information to accomplish multiple user equalization and interference suppression in the challenging scenario of an asynchronous random access ad hoc network. The proposed method has the advantage of allowing the transmission of complex data over time-dispersive multipath channels. A simulation example is presented that corroborates the interference suppression capabilities of the algorithm.
