Abstract:

An adaptive receiving array for rejecting interference in a coded communication system is described and computer simulations are presented which illustrate basic properties of the array processor. The array automatically forms a beam in the direction of a signal bearing the proper code modulation and forms nulls in the directions of signals bearing improper modulation. The communication signal present at the array input is assumed to be biphase 0-180 degrees modulated by the modulo-2 sum of a periodically-repeating code and a data sequence. The code is assumed known at the receiving site and is the means by which array distinguishes between desired and undesired signals.
