摘要： A dipole antenna for use with a mobile subscriber unit in a wireless communications system. The antenna is fabricated with printed circuit board (PCB) photo-etching techniques for precise control of the printed structure to mass produce antenna elements with repeatable features. The antenna includes a planar substrate made of dielectric material. A conductive planar element layered on one side of the substrate, and a conductive planar ground patch is located on the other side of the substrate. The conductive planar element is located in an upper region of the substrate, while the location of the planar ground patch is offset from the conductive planar element in a lower region of the substrate. A feed strip is connected to the conductive planar element, extends from the element to a bottom edge of the substrate, and terminates at a bottom feed point. The conductive planar ground patch includes two portions. One portion extends from the midsection of the other portion to the bottom edge of the substrate and provides a connection point for coupling the conductive planar ground patch to a ground plane which is aligned orthonormally to the substrate. Capacitive coupling between the conductive planar element and the conductive planar ground patch creates a junction which provides an upper dipole feed point in a mid-region of the substrate such that the conductive planar element acts as a first element of an unbalanced dipole antenna and the conductive planar ground patch acts as a second element of the unbalanced dipole antenna. The unbalanced dipole antenna forms a beam which may be positionally directed along a horizon that is substantially parallel to the ground plane.

摘要： A method for setting optimal phase settings for a plurality of antenna elements of a subscriber unit in a CDMA cellular telephone system includes the steps of detecting a received pilot signal at each of the plurality of antenna elements, combining the received pilot signal detected at each of the plurality of antenna elements with a summation circuit to produce a combined received pilot signal, determining a quality metric for the combined received pilot signal and adjusting phase settings of at least one of the plurality of antenna elements on the subscriber unit in response to the quality metric of the received pilot signal. These steps are repeated until the determined quality metric of the combined received pilot signal reaches a maximum.

摘要： An antenna apparatus which can increase capacity in a cellular communication system. The antenna operates in conjunction with a mobile subscriber unit and provides a plurality of antenna elements, each coupled to a respective programmable phase shifter. The phase of each antenna element is programmed for optimum reception during, for example, an idle mode which receives a pilot signal. The antenna array creates a beamformer for signals to be transmitted from the mobile subscriber unit, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference. Various techniques for determining the proper phase of each antenna element are accommodated.

摘要： The present invention provides for making code rate adjustments and modulation type adjustments in a pseudonoise (PN) encoded CDMA system. Coding rate adjustments may be made by changing the number of information bits per symbol, or Forward Error Code (FEC) coding rate. A forward error correction (FEC) block size is maintained at a constant amount. Therefore, as the number of information bits per symbol are increased, an integer multiple of bits per epoch is always maintained. The scheme permits for a greater flexibility and selection of effective data rates providing information bit rates ranging from, for example, approximately 50 kilobits per second to over 5 mega bits per second (Mbps) in one preferred embodiment.

摘要： A communications system improves performance of detecting a signal having an indication of a request to change communications states by making at least two positive identifications of the request in a given time frame. The system may further improve performance by applying a difference in power levels for a non-request state (i.e., steady state or ‘control hold’ state) versus a request state (i.e., ‘request to change’ state). In one particular application, a base station determines a request to change communications states with a reasonably high probability of detection and a reasonably low probability of false detection. The system has a reduced number of erroneous communications states, such as erroneous traffic channel allocations. The detection technique is compatible with 1xEV-DV systems and I-CDMA systems, but general enough to support systems employing various other communications protocols used in wired and wireless communications systems.

摘要： A subscriber controlled registration protocol, a subscriber monitors a congestion indicator signal broadcasted by a base station with which it desires to register. If the congestion indicator signal indicates that the base station is operating in a congested state, the mobile station selects another base station in the system. Otherwise, it attempts to register with the first selected base station.

摘要： A method for operating a subscriber unit that communicates with a code division multiple access (CDMA) wireless network is provided. At the subscriber unit, synchronization information is encoded with a CDMA code. The CDMA encoded synchronization information is transmitted from the subscriber unit in discrete repeating intervals. The discrete repeating intervals are separated by other discrete repeating intervals during which the subscriber unit does not transmit synchronization information.
