%X In the traditional schemes, the collided packets will be discarded and retransmitted, which results in a lower performance. In this article, Generalized Hybrid Forward Packets Collision Resolution (GHF-PCR) scheme based on virtual-MIMO techniques is studied and discussed. A kind of theoretic analytic model is established, and two kinds of cooperative nodes selection algorithms are also improved. Two PCR schemes are proposed and the average capacity, packets error rate, slot equivalent throughput and optimal transmission probability are analyzed. The proposed schemes could support random amount of collided nodes by selecting cooperative nodes to form virtual parallel channels and hence can deal with the collisions. The simulation results show that the proposed schemes can obtain better performance gain and be used in broader domain of application comparing with traditional schemes and other congener ones.
