摘要
With the great demand for broadband communication in high speed railway, new access technologies should be adapted to high mobility which brings Doppler frequency shift and fast handoff. The definition of cooperative range is presented and its influence on network connectivity is studied. The result shows that cooperation can greatly extend a wireless user's communication range. A novel scheme of cooperative access architecture is proposed to support high-speed users with broadband communication.
