DATA TRANSMISSION SYSTEM AND ITS RECEIVING DEVICE

摘要: PURPOSE:To realize the intermittent reception while performing an arithmetic mean by deciding transmission starting time of a data block based on end preamble when this is detected and applying to for each block. CONSTITUTION:When started, feed started feeding part B carrier detector 12 outputs detection pulse. Then power applied C sensed. The output (c) received from dropped down L answer DELTAt passes discontinuation preamble. averaging process circuit 15, edge used as start point Thus, possible even in system together with extreme reduction consumption.
