According to the characteristics of multipath energy, we proposed a phase detection energy detection algorithm of adaptive equalization cancellation based on wireless sensor network. The signal and channel models of wireless sensor net-work were established. The adaptive equalization algorithm was designed, and the adaptive FIR filter was used. The phase detection method was used for the UWB channel optimization and energy detection. Simulation result shows that the new method can overcome the influence of lag reduction of wireless sensor network channel, the network consumption is re-duced greatly, and the energy detection performance is improved, also the channel communication efficiency is improved in predominance, research results realize the optimization design of wireless network channel.
