Abstract: In order to improve the ability of data exchange and balanced scheduling in power network, a balanced switching algorithm based on baud interval equalisation and channel distortion compensation is proposed. The data exchange channel model of IP multimedia subsystem in power network is established. Combined with the matched filter detection method, the process of IP multimedia subsystem (IMS) balanced switching in power grid is filtered and detected. The diversity decision feedback equaliser is constructed to realise the data exchange channel compensation and automatic identification of IP multimedia subsystem in power grid, and the optimisation of IMS balanced switching algorithm in power grid is realised. The simulation results show that this method has good adaptability, low output error rate and good ability of IMS data balance exchange and scheduling.

Keywords: power network; IMS; IP multimedia subsystem; balanced switching; anti-interference design; baud interval equalisation; channel distortion compensation.
