METHOD AND SYSTEM FOR CONTROLLING A RECEIVER IN A DIGITAL COMMUNICATION SYSTEM

摘要

Detection method and device for a receiver in a digital communication system designed to process a frame comprising a periodic sub-set of length n, said method comprising the following steps: - determining a first vector u having a length n; - determining a second shifted vector v; - calculating a correlation function between said first and second vectors; - calculating a quadratic error function between said first and second vectors; - calculating a first cost function that is a linear combination of both preceding functions and, according to the sign of the result, - calculating a second cost function of frame beginning estimate; and - starting the communication system receiver.
