Abstract
A method for determining the initial state of shift registers constituting a modular type or simple construction type maximum length linearly occurring code sequence generator used in a spread spectrum communication system is disclosed, by which it is determined by the following equation; ##EQU1## where yj(0) is the j-th element of Y (0), and PA1 X=P X (0).
