摘要：In a discrete tone system, a base station receives a transmission burst from aremote unit being installed that includes delay compensation pilot tones that areuniformly spread throughout the transmission bandwidth. The arrival time transmissionburst is not synchronized with the other remote units transmitting to the base station.
The base station measures the phase delay of each tone and calculates the delay of theremote unit from the slope of the line of phase angle versus tone frequency. The basestation transmits a signal to the remote unit that includes the magnitude and direction ofthe delay, which allows the remote unit to adapt the timing of its transmission to besynchronized with the other remote units.
