SYNCHRONIZATION SYSTEM FOR A WIRELESS RECEIVER

A synchronization system for initial setup of phases of local oscillators in a wireless receiver of a communication system characterized by transmission of data packets having a predetermined preamble consisting of M identical sections of L symbols followed by a single section of the same kind, multiplied by −1, and wherein the wireless receiver is operative to perform decimation in an RF demodulator. The synchronization system includes a twofold correlator, an accumulator, a multipler, a threshold comparator, a carrier phase former and a clock phase former, and operates at a decimated symbols frequency, and performs not only preamble detection, but also symbols clock phase detection together with carrier phase detection, while enabling the theoretically possible noise immunity.
