IPC: H04B7/26
Filed: 2000-08-16
Abstract: A method and circuit for adaptively estimating channel conditions of a pilot channel in a wireless communication system. The method includes estimating channel statistics of the pilot channel, and adaptively filtering the pilot channel in response to the estimated channel statistics. The estimation is performed by filtering a channel signal derived from the pilot channel to determine an estimated channel mean and an estimated channel covariance. In order to perform the adaptive filtering, the present invention partitions the pilot channel into one or more time slots and weights each time slot according to the channel statistics. Thus, an advantage of the present invention is that it automatically and continually updates the pilot filter parameters in order to optimize the pilot filter performance over a broad range of channel conditions.

Title: Method and apparatus for beamforming in a wireless communication system
IPC: H04B7/06
Filed: 2000-08-31
Abstract: In a CDMA data communication system capable of variable rate transmission, utilization of beamforming techniques decreases the average interference caused by transmissions of a base station (104) to subscriber stations (112) in neighboring cells (124). Base stations (102, 104) utilize multiple transmit antennas (106, 108), each transmitting signals at controlled phases, to form transmit signal beams (110, 118, 122) corresponding to individual subscriber stations (112, 116, 114). Data and reference signals are transmitted along beams (110, 118, 122) that change according to fixed time slots and subslots in order to maximize carrier-to-interference ratios (C/I) measured at subscriber stations (112, 116, 114).

Title: Indication system for vehicle
IPC: B62D57/02
Filed: 1995-02-03
Abstract: There is provided, in a preferred embodiment, a transportation vehicle for transporting an individual over ground having a surface that may be irregular. This embodiment has a support for supporting the subject. A. ground-contacting module, movably attached to the support, serves to suspend the subject in the support over the surface. The orientation of the ground-contacting module defines fore-aft and lateral planes intersecting one another at a vertical. The support and the ground-contacting module are components of an assembly. A motorized drive, mounted to the assembly and coupled to the ground-contacting module, causes locomotion of the assembly and the subject therewith over the surface. Finally, the embodiment has a control loop, in which the motorized drive is included, for dynamically enhancing stability in the fore-aft plane by operation of the motorized drive in connection with the ground-contacting module. Included in the control loop is a directional control, letting the vehicle move, lean and turn in response to an indication of the subject, e.g. that of leaning the vehicle. The ground contacting module may be realized as a pair of ground-contacting members, laterally disposed with respect to one another. The ground-contacting members may be wheels, a duster of wheels, or includes rotatably mounted arcuate element pairs.

Title: Apparatus and method of implementing a universal home network on a customer premises isdn bus
IPC: H04Q11/04
Filed: 2000-09-05
Abstract: An arrangement for implementing a network in an ISDN-based customer premises having a four-wire ISDN S0 bus. The ISDN-based customer premises includes a Network Termination Basic Access (NTBA) that interfaces between the residential customer premises and the public switched telephone network or a similar connector for internal S0-Busses within a PBX system by mapping the two-wire ISDN signal onto the four-wire bus. A low pass filter is added to the two-wire send path to eliminate high frequency noise caused by harmonic reflections of the ISDN-based signals on the four-wire bus. Filters are also coupled between each ISDN device and the four-wire S0 bus, ensuring that the four-wire S0 bus is isolated from the ISDN devices to optimize transmission of the higher frequency home network signals. The two-wire home network signals are also split by S0 transformers for transmission on the two-wire send path and the two-wire receive path of the four-wire S0 bus, effectively increasing the transmission wire radius for improved reception of the home network signals.
