An adaptive array technique for AM signals

This report discusses a method of using an adaptive array with AM signals. A technique is suggested in which phase modulation is added to a conventional AM signal to make it possible to separate the desired signal from interference. The new signal will be transmitted in the same bandwidth as the conventional AM signal and hence can be intermixed with standard signals in a communication net. Digital simulations of such a system have been done and a few of the results are shown in this report. These results indicate that the array will provide suitable interference protection with such signals.
