BLIND CARRIER OFFSET DETECTION FOR QUADRATURE MODULATED DIGITAL COMMUNICATION SYSTEMS |
摘要 |
A system and method for estimating the frequency offset experienced between carrier and local oscillator frequencies in communication systems using quadrature modulation. The invention exploits the geometry of the quadrature modulation constellation and estimates actual offset within a predefined carrier offset value without requiring data estimation.
