A wireless communication system and a method for reducing a ranging time. The communication system includes a main synchronization block group which processes the transceived signal and determines whether the transceived signal is a signal desired by a transmitting device when a receiving device re-transmits the transceived signal to the transmitting device; a ranging block which measures a distance between the transmitting device and the receiving device using a ranging signal when the transceived signal is the desired signal of the transmitting device based on the determination of the main synchronization block group and when the transceived signal is the ranging signal; and a symbol synchronization block which detects a start point and an end point of a symbol forming the signal when the transceived signal from the receiving device is a data communication signal. Accordingly, the fast ranging is feasible and channel occupation time can be shortened.

Wireless communication system for reducing ranging time

A communication system which transmits and receives a communication signal having an intra-guard-interval (IGI) inserted is provided. The communication system includes a signal generator which is configured to generate a signal to carry data; and a signal output part which is configured to split a symbol period, which is a transmission unit of the communication signal into a plurality of sections, and to selectively insert the signal which is generated into the plurality of sections, and to output the communication signal.

Communication system for transmitting and receiving a communication signal having an intra-guard-interval

A ranging system and ranging method are provided. The ranging system includes a transmission signal generator which generates a transmission signal, which is transmitted from a transmission device to a reception device; a correction signal generator which converts the transmission signal, which is processed in the reception device and re-input to the transmission device, into a correction signal; a reference signal generator which generates a reference signal, an overlap detector which detects an overlap region between the correction signal and the reference signal; a time calculator which calculates a transmission time of the transmission signal; and a distance calculator which calculates a distance between the devices using the transmission time. The method includes generating a transmission signal; transmitting the transmission signal to a reception device and receiving the signal back again; producing a correction signal; detecting an overlap region between the correction and reference signals; calculating a transmission time; and calculating a distance between the transmission and reception devices.
