Abstract :
A correlation is proposed for use to detect time and frequency offsets in a received signal in a digital transmission system. Applications include time and frequency synchronization in a single frequency network; pre-distortion for high power amplifiers in a transmitter. The correlation is formed with the products of two pairs of transmitted samples and received samples. The same correlation can be used to detect both time and frequency offsets in the received signal.
