Abstract: The calculations of the lowest radiant intensity of transmitter of the wireless diffuse infrared data communications are introduced which satisfy the request of error rate according to the receiver's lowest sensibility . This communication system is applied to the infrared fuse in one complex form. In consideration of internal and external interference in its practical application, which are solved by combining software and hardware.

Key words: coding modulation, IR communication, anti-interference
