1. A method of performing time synchronization in a communication system, comprising:

  • measuring an arrival time of a transmission received via a communication channel using spectral estimation, wherein the measuring the arrival time of the transmission comprisesobtaining a channel estimate for the communication channel, andperforming spectral estimation on the channel estimate to obtain the measured arrival time for the transmission;

    determining a time error between the measured arrival time and a desired arrival time for the transmission; and

    generating a time adjustment based on the time error.
