Abstract: A key challenge for power communication wireless communication is to transmit control information with very high reliability and low delay.However,the existing wireless communication based on single channel is not easy to resolve the issue due to the fading and interference properties of wireless channel.In this paper,we work out a model of CRC-RS encoding-based wireless dual channels,in which the channels are independent in fading and interference.Simulation result shows that wireless dual channels have very lower error and delay compared with single channel and existing papers.Wireless communication using multi channel might solve the communication issue in industrial environment.
