Abstract  Abstract

In a direct sequence spread spectrum modulator a signal orthogonalizer comprising:
pilot channel signal generator means for generating a pilot signal according to a first orthogonal function; and
communication channel signal generator means for receiving an input information signal generating an orthogonal function signal according to a second orthogonal function combining said orthogonal function signal with said input information signal to provide a resultant communication channel signal.
