Abstract
A signal matching apparatus and method in a communication system are provided. For signal matching, a transmitter generates a synchronization code for synchronization acquisition, includes the synchronization code on a center frequency subcarrier of a transmission signal, and sends the transmission signal to a receiver. The receiver detects the synchronization code from the center frequency subcarrier of the received signal and performs signal matching to the transmitter using the synchronization code.
Claims32
A signal matching method in a communication system, comprising:
- generating a synchronization code for synchronization acquisition;
- and
- including the synchronization code on a center frequency subcarrier of a transmission signal and sending the transmission signal to a receiver, for signal matching.
A signal matching method in a communication system, comprising:
- receiving a signal including a synchronization code for synchronization acquisition;
- detecting the synchronization code from a center frequency subcarrier of the received signal;
- and
- performing signal matching to a transmitter that sends the synchronization code, using the synchronization code.
A signal matching method in a communication system, comprising:
- measuring transmission signals to be sent through a wired link and a wireless link and measuring reception signals received through the wired link and the wireless link;
- sending the transmission signals through the wired link and the wireless link by compensating for the difference between transmission timings of the transmission signals so that the transmission timings are synchronized to each other;
- and
- receiving the reception signals through the wired link and the wireless link by compensating for the difference between reception timings of the received signals so that the reception timings are synchronized to each other.
The signal matching method of claim 19, wherein compensating for the difference between the transmission timings of the transmission signals comprises delaying at least one of a first signal to be sent through the wired link and a second signal to be sent through the wireless link so that the transmission timings are synchronized to each other.
The signal matching method of claim 19, wherein compensating for the difference between the reception timings of the reception signals comprises delaying at least one of a first signal received through the wired link and a second signal received through the wireless link so that the reception timings are synchronized to each other.
A signal matching apparatus in a communication system, comprising:
- a transmitter for generating a synchronization code for synchronization acquisition, including the synchronization code on a center frequency subcarrier of a transmission signal, and sending the transmission signal to a receiver, for signal matching.
A signal matching apparatus in a communication system, comprising:
- a receiver for receiving a signal including a synchronization code for synchronization acquisition, detecting the synchronization code from a center frequency subcarrier of the received signal, and performing signal matching to a transmitter that sends the synchronization code using the synchronization code.
A signal matching apparatus in a communication system, comprising:
- a signal measuring portion for measuring transmission signals to be sent through a wired link and a wireless link and measuring reception signals received through the wired link and the wireless link;
- a signal compensator for compensating for the difference between transmission timings of the transmission signals so that the transmission timings are synchronized to each other, and compensating for the difference between reception timings of the received signals so that the reception timings are synchronized to each other;
- and
- a controller for receiving transmission signal measurements and reception signal measurements from the signal measuring portion and controlling the signal compensator to compensate for the difference between the transmission timings of the transmission signals and compensate for the difference between the reception timings using the transmission signal measurements and the reception signal measurements.
