摘要
Communication Network and Signal Processing are two of the research hotspots in the field of information technology because of their fast development. This paper focuses on the introduction of some research progresses in our National 863 Project based on the combination of technologies in these two areas. We present two new Medium Access Control （MAC） protocols based on so-called Multi-Packets Reception （MPR） in Ad hoc networks. Communication in the first scheme is initiated from senders and from receivers in the second one. Simulation results show that these new MAC protocols, which are based on new signal processing techniques, may raise network capacity and reduce transmission delay of data from end to end.
