Abstract
A maximum length shift register sequence generator capable of changing the format and phase of an M code known as maximum length shift register sequences in the transmitter and receiver. The register is most suitable for use in spread spectrum communication systems adapted to effect transmission by correlation between an M code from the transmitter and such an M code generated in the receiver. The generator includes a latch for storing the format and initial phase of an M code to be generated subsequently, and a microprocessor for setting in the latch necessary data required for changing the M code. A change of the M code is effected by a strobe signal lasting for a time equal to the lasting time of one clock pulse.
