Abstract:

An integral equation for calculating exact signal processing loss in direct-sequence PSK-modulated, pseudonoise, spread spectrum digital transmission, caused by passband amplitude andor phase distortion is derived in closed form. Methods for computer-assisted or manual means of evaluating the integral are worked out in several examples taken from operational satellite systems hardware. Procedures, design tables, and computer programs are provided for combinations of passband distortion and signal spectrum-weighting characteristics. Passband distortion specification and allocation is considered, analyzed, and discussed. Author
