Abstract
Reliability of wireless communication can be improved by utilizing various diversity schemes, which are seriously desired by the heavy haul railway transportation systems. The transmission of control message is a significantly vital issue and suffers from severe channel fading and interferences, which may result in failures of locomotive control. This paper proposes a novel hybrid cooperative scheme to increase the diversity gain of wireless transmission, which can guarantee higher degree of coordination among multiple locomotives. With multiple independent transmission paths, the outage probability falls down exponentially with Signal-to-Noise Ratio (SNR). Simulation results illustrate the significant performance gain.
