1. A method of frame synchronization, comprising the steps of:

  • storing a first n bits of a digital signal into a current frame memory;

    shifting n-m of the first n bits into a previous frame memory;

    storing a second n bits of the digital signal into the current frame memory;

    comparing at least one bit from the current memory with at least one bit from the previous memory;

    incrementing a state counter when a condition of the comparison is successful; and

    comparing the state counter to a threshold such that the result is indicative of frame synchronization.
