Multiple packet reception (MPR) has become a promising technique to considerably improve the throughput in a wireless network due to its provided collision resolution capability. In this paper we present a blind algorithm to separate several data packets exploiting its asynchronous nature. The separation algorithm consist on finding a minor subspace for each of the data packets in the received mixed signal, this will lead to an equalizer which reduces multiple access interference (MAI), up to a phase ambiguity on the desired data packet. A variant algorithm, with low training and no added complexity, that deals with the case of synchronized data packets is presented.
