WCDMA 3D Location Determination with 3D Polarization Using Four 3-element Arrays
A 3D location determination method uses only four 3-element arrays, each 3-element array consists of three orthogonal dipoles to achieve the vertical, horizontal and orthogo-nal one to both of them. The non line-of-sight path would change the polarization at the receiver which can affect the quality and the strength of the received signal. This method is proposed for WCDMA mobile systems which are commonly used in the 3G. The receiver RAKE is used to identify the multipath and the time delay between the elements for each polarization state. Depending on the geometrical distribution of the four arrays, the phase shifts are determined for each path. Knowing the phase shift between the elements helps to find the Direction of Arrival (DOA) for each path. The path distance is determined via the traveling time of the message response between the transmitter and the receiver. The received signals of the antenna elements are combined on the MRC for signal maximization also.
