Abstract:

Based on the analysis of the interference between the Base Station(BS) and wireless microphones(WMs) and the interference between Consumer Premise Equipments(CPEs) and WMs in Wireless Regional Area Network(WRAN), a new WRAN-WM coexistence model is established. A mathematical model of subchannel allocation in a single cell of WRAN is established which target is maximize the data transmission rate for downlink of system. Modeling the subchannel allocation as finding maximum matching graph of the bipartite graph, we get the optimal solution to employs Hungarian algorithm based on the graph theory to solve the problem which is a mixed-integer nonlinear programming. The simulation results show that the proposed scheme is very effective.
