Abstract

A blind method for jointly estimating and correcting time, carrier frequency and sampling clock frequency synchronization in OFDM based systems is proposed. The algorithm is particularlly suitable for low-cost terminal implementations, since it provides a great efficiency in terms of hardware complexity. Its performance has been tested on a real system, taking 3GPP-LTE as target technology and FPGAs as hardware platform. Results show its good performance while keeping computational complexity unincreased.
