  • Patent number: 10313927
    Abstract: In the present invention, data generated from a source unit are distributed to at least one bandwidth; the data distributed to the respective bandwidths are encoded in order to perform an error correction; the encoded data are distributed to at least one antenna; a subcarrier is allocated to the data distributed to the respective antennas, and an inverse Fourier transform is performed; a short preamble and a first long preamble corresponding to the subcarrier are generated; a signal symbol is generated according to a data transmit mode; and a frame is generated by adding a second long preamble between the signal symbol and a data field for the purpose of estimating a channel of a subcarrier which is not used.

  • Patent number: 6459903
    Abstract: A method of locating a mobile station is provided. In the present invention, the mobile station is capable of communicating with at least three base stations, each having at least two antennas. To estimate the location of the mobile station, the distance between the mobile station and each base station is calculated based on the time of arrival (TOA) of a mobile station signal at the base station, a first estimated MS location area is defined as an overlap area of circles of which the radiii are the distances between the MS and the base stations. Then, the location of the mobile station is estimated based on the time of signals received through the two antennas of each base station and based on the angle between the antennas of each base station and the mobile station. Here, the angle is calculated from the phase difference between the received signals and a communication frequency of the signals. A second location area is defined as an area defined by lines connecting the base stations to the mobile station.
