摘要： An output of an equalizer is decoded to produce first decoded data having a first accuracy. The output of the equalizer is further decoded to produce second decoded data having a second accuracy, and the second accuracy is greater than the first accuracy. Tap weights for the equalizer are calculated using the first and second decoded data. The calculated tap weights are applied to the taps of the equalizer.

摘要： A method, a network base station, and a user communication device for transmitting data on an orthogonal frequency-division multiplexing carrier are disclosed. An antenna array may transmit a signal decodable by a legacy user communication device designed for compatibility with a legacy set of transmission antennas. A processor 210 may encode a subframe of the signal with a legacy set of common reference symbols and a supplemental set of common reference symbols referring to the antenna array.

摘要： A certificate for animal data is provided in a network environment. Initially, animal data is stored in a database. The stored animal data is then displayed for verification. The displayed data is verified by a user independent of animal ownership. Finally, a certificate that comprises the verified animal data and a signature field is issued such that, if signed, the certificate provides assurance of the verification of the animal data.

摘要： A method (1700) and apparatus (1801) provide channel estimation with extended bandwidth filters. Antenna (1813) receives a signal such as a pilot signal and detects a bandwidth associated with the pilot signal in a detector (320). One of a plurality of filters (603, 605, 607, and 609) including extended bandwidth filters (311) and a default filter (305) can be selected by a selector (617). If the detector detects activity associated with a wider bandwidth, the filter associated with the wider bandwidth is selected over the presently selected filter. If no activity is detected, the default filter is selected.

摘要： To address the need to convey ACK/NACK information in a manner that conserves system and signaling resources, embodiments of the present invention employ a Node-B transmitting on two types of ACK/NACK broadcast channels (501, 502), one type for received uplink data that was scheduled by the Node B and the other type of broadcast channel for received uplink data that was not scheduled by the Node B. Other embodiments of the invention employ a Node-B transmitting on two types of broadcast channels, one type of broadcast channel for received uplink data that comes from non-SHO users and another type of broadcast channel for received uplink data that comes from non-scheduled users or comes from scheduled SHO users. In addition, ACK/NACK information is scheduled (800) into the available broadcast channel time slots in accordance with a transmission priority that is determined by a scheduler.

摘要： Power control bit generation for forward link power control in a spread spectrum communication system is accomplished through modification of a set point threshold. Modification of the set point reduces the number of squaring and division mathematical operations, thus more efficiently utilizing limited system resources in a mobile receiver used in forward link power control.

摘要： In a code division multiple access wireless communication system having at least one base transceiver station and at least one mobile station having a mobile station receiver assembly configured to receive a coded signal having an information-bearing signal portion and an associated interfering signal portion from the base transceiver station, a method and apparatus for automatic gain control compensation in the mobile station receiver assembly, is disclosed. The method includes causing a gain adjustment to the coded signal by an AGC circuit in the mobile station receiver assembly to produce a post-AGC signal having a post-AGC interfering signal portion with an associated post-AGC interfering signal power level, and an associated gain error value. The method further includes compensating for the gain adjustment to the coded signal if the number of receiver fingers assigned to demodulate the coded signal is less than or equal to a predetermined number.
