Abstract
This paper describes a highly parallel system of computational processors specialized for real-time adaptive antenna nulling computations with many degrees of freedom, which the author calls MUSE, and a specific realization of MUSE for 64 degrees of freedom. Each processor uses the CORDIC algorithm and has been designed as a single integrated circuit. Ninety-six such processors working together can update the 64-element nulling weights based on 300 new observations in only 6.7 milliseconds. This is equivalent to 2.88 Giga-ops for a conventional processor. The computations are accurate enough to support 50 dB of S/N improvement in a sidelobe canceller. The connectivity between processors is quite simple and permits MUSE to be realized on a single large wafer, using restructurable VLSI. The complete design of such a wafer is described. >
