Abstract
A communications method including the steps of: receiving signals from at least one signal source during a first signal source transmission; estimating at least one signal source parameter based on the received signals during the first signal source transmission; receiving signals from at least one signal source during a second signal source transmission; and determining a difference between the first and second signal source transmissions using the at least one estimated signal source parameter.
