This paper presents a novel of Complex Coefficient Linear Phase (CCLP) Infinite Impulse Response (IIR) filter. The detailed algorithm is provided, and the linear phase feature of the CCLP is proved mathematically. The algorithm can be widely used in the IIR filters for communications. Its application includes interference cancellation filter, image reject filter, etc.
