Description
Summary:We consider multiple packet reception (MPR) for asynchronous random access wireless mobile ad hoc networks. An interference cancellation algorithm is proposed that exploits the baseband cyclostationarity properties of the signal, which are induced at the transmitters by means of modulating the symbols with distinct polynomial phase sequences. In contrast to the method presented in van der Veen et al. (2002), the proposed technique does not require knowledge of the starting time of transmission of the desired signal and can be applied to dispersive multipath channels. Also a practical way of assigning the modulating sequences via the use of a common codebook known to all nodes is proposed, and the impact on local throughput of such a scheme is analyzed.
