Pilotless timing recovery for baseband multicarrier modulation

This paper describes a multicarrier modulation timing recovery algorithm that does not require use of a designated pilot tone. Instead, all or some received subchannels are used to estimate phase and frequency errors. Algorithms for both acquisition and tracking are presented, and simulation results...

Summary:This paper describes a multicarrier modulation timing recovery algorithm that does not require use of a designated pilot tone. Instead, all or some received subchannels are used to estimate phase and frequency errors. Algorithms for both acquisition and tracking are presented, and simulation results show excellent performance. The algorithm provides a useful timing recovery approach for environments in which use of a designated pilot is infeasible or undesirable, such as on digital subscriber lines corrupted by high levels of broadcast AM or amateur radio interference.
