ABSTRACT:
A method and apparatus for bit synchronization and error detection uses bit rotation of a received data burst and division by a polynomial generator to produce a syndrome. Syndrome corrector logic steps and circuitry determine the bit slippage and correct the syndrome for the slippage to produce an error syndrome. If there are no errors, the bit slippage value is used to synchronize the received data burst.
