1. A method for compensating for phase shifts of a communication signal, comprising:

  • determining a first reference signal at a first location along a transmission path and a second reference signal at a second location along the transmission path, the second reference signal having the same phase as the first reference signal;

    determining at the first location a first phase offset using the first reference signal and a first communication signal;

    determining at the second location a second phase offset using the second reference signal and a second communication signal; and

    adjusting at the second location a phase of a third communication signal using the first and second phase offsets to obtain a modified communication signal;

    wherein the first, second, and third communication signals are the same communication signal obtained at different locations along the transmission path.
