    Abstract: A method and apparatus generated soft values from a co-channel differentially encoded received signals. The soft values are generated by determining jointly detected symbols and corresponding joint metrics. A first potential nondetected metric sum is determined by flipping the current desired coherent detected symbol and keeping the interfered coherent detected symbol as is. A second potential nondetected metric sum is determined by flipping the previous desired coherent detected symbol and keeping the interfered coherent detected symbol as is. A minimum between the difference of the detected jont metrics and the two nondetected joint metrics is found. The soft values are then established based on the minimum difference metric.

    Abstract: A cellular radiotelephone base station communicates with cellular radiotelephones by receiving cellular radiotelephone communications energy (601) from cellular radiotelephones on an antenna array (510), processing (610) the received communications energy to produce at least three processed radiotelephone communications signals (611) representing communications energy received from a coverage sector, and selecting (620) at least two of the processed signals (621) for decoding (630) in a conventional decoder. Preferably, the selected signals are the processed signals having the highest power or signal quality. Diversity gain is achieved by processing the received communications energy to produce at least two processed first polarization signals representing received communications energy having a first polarization and at least two processed second polarization signals representing received communications energy having a second polarization, and selecting at least one of the processed first polarization signals and at least one of the second polarization processed signals for decoding. Preferably the selected processed first polarization and second polarization signals are the signals from each polarization having the highest power or signal quality.

    Abstract: Method and apparatus for two-user join demodulation in a system having transmit diversity. A receiver includes at least a detector unit (1513) and a channel estimation unit (1512), and exploits transmit diversity employed by at least one of two users or transmitters on a channel. Symbol detection (301, 401, 601, 701, 901, 1101, 1301) and channel estimation (303, 403, 603) are performed in block or batch fashion, or recursively on a symbol-by-symbol basis. Joint detection makes use of transmit diversity by at least one of the transmitting users. Channel estimates can be updated using channel tracking (904, 1304). If the signals from the first user and the second user are asynchronous, detection can be accomplished in part through reference to a pulse-shape component. The receiver may be incorporated into a mobile communication terminal.

    Abstract: Methods of demodulating a received signal are disclosed in which an interference map containing information regarding a plurality of candidate co-channel interference sources is provided. The information in the interference map regarding the plurality of candidate interference sources may be used to identify any of the candidate co-channel interference sources that comprise a dominant interference source. The received signal may then be demodulated in a manner that cancels at least part of the contribution of any identified dominant interference source by using the information regarding any such interference source contained in the interference map.

    Abstract: A method of supplying channel information in a wireless communication system comprises a mobile terminal normally providing a basic channel report to the wireless communication system; the mobile terminal receiving at least one common feedback criterion broadcast to a plurality of mobile terminals; the mobile terminal determining if the mobile terminal satisfies a condition based on the at least one common feedback criterion; and the mobile terminal selectively providing an enhanced channel report to the wireless communication system based on the determining. The basic channel report may comprise information related to a first set of channel parameters, and the enhanced channel report may provide greater detail on the first set of channel parameters and/or relate to a second set of channel parameters. A method of a base station adaptively controlling channel information reporting by broadcast transmitting at least one common feedback criterion is also presented.

    Abstract: Method and apparatus for demodulation in a system having known frequency offsets. First and second signals from two users occupy substantially the same bandwidth and use substantially the same carrier frequency, while the relative frequencies of the signals on different transmit antennas associated with a base station are adjusted to have known, specific frequency offsets. These known frequency offsets are used at the receiver to aid in estimating any known frequency errors and to demodulate the multiple transmitted signals. In addition to being useful for demodulation, known frequency offsets can be assigned to each of a plurality of base stations to facilitate identification of a particular base station. The approach can be used for any type of time domain multiple access (TDMA) system, including Global System for Mobile (GSM), or for code division multiple access (CDMA) systems.
