发明名称 Method and apparatus for determining directionality of communication signals on a communication channel
摘要 In a bidirectional communication channel, the method and apparatus for determining directionality of communication signals using digital techniques. A plurality of independent signals are derived from the communication channel, which signals are analyzed to determine their relative phase(s). The relative phase(s) are then compared with a table of relative phases indicating the directionality of the original signals.
