1. A spread spectrum communication system, by which demodulation of necessary information is effected by correlation output between signals for which spectrum of information signals is spread by using a maximum length linearly occurring code sequence on the sender side and a maximum length linearly occurring code sequence generated on the receiver side, wherein the initial state of shift registers constituting the maximum length linearly occurring code sequence generator is determined by the following equation;

  • ##EQU11## j=1, . . . , n whereyj(0) is the j-th element of Y(O),X is the j-th row, andX=PX(O).
