摘要： Mobile station positioning is implemented using various methods and devices. According to one example embodiment of the present invention, an azimuth angle estimation of the location of a mobile station is accomplished using a radio-signal processing apparatus. The azimuth angle is estimated with respect to a nearby base station that covers a service area using common sectorization via multiple directional antennas respectively transmitting at different azimuth angles. The apparatus has a memory for storing information that associates directional sector antennas of the nearby base station and expected antenna radiation gains in the common sectorization service area corresponding to locations relative to the nearby base station. The apparatus also includes a processor arrangement that determines received signal strengths of respective signals received from different ones of the directional sector antennas of the nearby base station and that determines estimated azimuth angles by comparing the stored information with the received signal strengths.

摘要： A device and method for locating a mobile station (MS) in a mobile communication system. In the MS locating device, a first antenna and a second antenna of a base station (BS) are spaced from each other by a distance equivalent to a wavelength of an MS transmission channel multiplied by a predetermined coefficient, such as one half. A first frequency downconverter and a second frequency downconverter convert signals received from the first and second antennas to baseband signals and digitize the baseband signals to chip sample data. A first channel demodulator and a second channel demodulator recover the chip sample data received from the first and second frequency downconverters and output information about the symbol start and PN code of a specific MS signal. A controller outputs a PN code for identifying the specific MS and finger position information based on the symbol start and PN code information received from the first and second demodulators. In addition, the controller may be supplied with orthogonal code information from the demodulator; in this case, the controller will output information concerning the specific Walsh code. A symbol data extractor extracts two symbols of the specific MS from the chip sample data received from the first and second frequency downconverters based on the PN code and finger position information. An incident angle estimator estimates the incident angle of the received signal from the phase difference between the extracted two symbols. A location estimator estimates the location of the specific MS based on the estimated incident angle and the round trip delay (RTD) measured for the MS.
