CW Interference Cancelling System for Spread Spectrum Signals.
Abstract
It is an object of the present invention to provide an improved noise coded communication system. Another object of the present invention is to provide an improved noise coded communication system which eliminates continuous wave or slowly varying continuous wave interfering signals. Still another object of the present invention is to provide an improved noise coded communication system which totally eliminates continuous wave or slowly varying continuous wave interference while experiencing no loss and substantially no degradation of the desired signal. And yet another object of the present invention is to provide a CW canceller for noise coded communication systems which is relatively small in size, weight and extremely low in cost. Accordingly, these and other objects are achieved by means of a variable delay line and a linear adder coupled to the receiver output of a multiplexed noise coded transceiver. The noise code comprises a multi-bit binary code having a code bit width TAU and which upon matched filter detection compresses to an impulse having a width TAU.
