The design of a high-speed complex signal processor is presented. It is based on a novel multiplier whose hardware implementation is shown to be characterized by simplicity, a high degree of parallelism, regularity, and modularity. The multiplier design is made possible by recent advances in the theory of performing polynomial multiplication in modular rings with reduced complexity. This latter development is based on the polynomial residue number system (PRNS). While traditional parallel complex multiplication requires four real multiplications, the proposed scheme is based on decomposing the process into eight smaller concurrent processes. If p is the performance of each of the four processors of the traditional technique and h is the investment in hardware required for its realization, the performance of each of the processors of the proposed method is 4p and its hardware investment is h/16.
