injection of an audio-frequency pilot
The CCID is configured to receive a pilot signal from the electric vehicle, the pilot signal conveying pilot information, and overlay additional information onto the pilot signal.
If the second pilot signal is present, it is used, in addition to the first pilot signal, for the SIR measurement of a high rate closed loop type of transmission power control.
As a result, the time required for the receiver (201) to acquire a valid pilot signal is significantly reduced.
A pilot signal generating unit (103) generates a pilot signal having a predetermined time-varying pattern and to be carried by a pilot carrier.
Otherwise, only the first pilot signal is used for the SIR measurement of the high rate closed loop type of transmission power control.
The method includes applying a pilot signal to a disturber twisted pair (102) and measuring near end crosstalk of a victim twisted pair (104).
An output circuit (20) sends out, to an input circuit (60), a control pilot signal generated by a voltage source (21).
Disclosed is a phase compensation device for a pilot signal of a lithium niobate modulator.
A transmitter generates a pilot having a constant time-domain envelope and a flat frequency spectrum based on a polyphase sequence.
A highly detectable pilot can be transmitted in one or more data symbols that are not currently being utilized for transmission of data.
