Based on a large number of computer simulations, this paper proposes to segment the frame synchronization code by using the least squares curve fitting and correction to obtain More accurate and reliable system channel real-time bit error rate, bit error rate detection processing provides a new way of thinking and methods. Combined with a digital microwave electronic anti-jamming issues, put forward the implementation of specific methods and steps.
