A transmission path delay measurement method, a simultaneous transmission system, and a communication receiver (Transmission Path Delay Measurements Using Adaptive Demodulation)

摘要

The simultaneous transmission system 100 provides a method and apparatus for automatic delayed dynamic measurement using adaptive demodulation. The simultaneous transmission system 100 includes a control station 101 and a plurality of remote transmission stations 201 and 301 capable of retransmitting a received delayed dynamic ranging measurement signal including at least a correction bit pattern signal and a subsequent synchronization pattern signal . A control station (101) includes a transmitter (131, 181) for transmitting a delayed moving picture measurement signal, a receiver (151, 191) for receiving a retransmitted delayed moving picture measurement signal; A correlation bit pattern analyzer 115,776-802 for analyzing the received correction bit pattern signal to derive a fine reception time correction coefficient, And a time corrector (115,804) for correcting the reception time by the fine reception time correction coefficient to obtain the corrected reception time of the delayed moving picture measurement signal at the control station (101).
