摘要： A wireless communications system base station (101), upon receiving (202) from a mobile station (102) a wireless transmission that comprises a suggested transmitter-receiver configuration, can respond (in appropriate instances) by automatically transmitting (203) to the mobile station a wireless transmission comprising an indication to use instead a default transmitter-receiver configuration. By one approach, the latter action can be based, at least in part, upon a determination regarding reliability (301) of that suggested transmitter-receiver configuration (which might comprise, for example, a direct or indirect measure of quality of the channel by the default transmitter-receiver configuration was received) to provide a corresponding reliability assessment. The latter can then be used (302) to determine whether to use this suggested transmitter-receiver configuration for a subsequent communication with the mobile station.

摘要： A method and system (102) provide adaptive modulation/coding with distribution of excess resources based on one or more system criteria. The system (102) may be any system with more than one modulation rate or more than one coding rate and may be a wireless communication system using CDMA, TDMA, OFDM or any other signal formats. Generally, the method determines excess resources of the system based on desired characteristics of links supported by the system. The excess resources may be any number of system resources, such as transmit power. These excess resources are then distributed to the links based on various system criteria, such as to increase system coverage, to increase system capacity, to modify a data rate profile of the system or to reduce interference in the system. Methods for providing such distribution of the excess resources are also provided for equal data rate systems.

摘要： The log-add kernel operation is represented as a summation of an average and a correction factor composed of a constant and a term based on a difference between the input arguments. In a described embodiment, the correction factor is approximated using the reduction of the correction factor into a Taylor series expansion, which may be defined around the difference between the input arguments as approximately zero. The approach may be further optimized to provide the Taylor series expansion as being modified to compute the correction factor with simple additions, multiplications, and shift operations. If the input arguments are close to each other, the new computed representation may be used, and if the arguments are further apart, the max operation is used. The log-add kernel operation also may be extended to more than two arguments, for application, for example, in the kernel operation of the generalized Viterbi decoder with a branch fan-in greater than 2. Additionally, a method of computing bit soft values for symbols of a higher-order modulation using log-add operations is disclosed, where each log-add is provided as an approximation including a primary term and a parameterized correction factor. Performance close to the optimal soft value generation is achieved at roughly the same complexity as the dual-min algorithm.

摘要： A window error detector for a receiver capable of operating in a discontinuous transmit mode includes a soft decision decoder (210) producing soft output and generating window error signals. A detector (214) is coupled to the soft decision decoder for detecting a bad frame when the window error exceeds a bad frame threshold, wherein the threshold is altered based on the discontinuous transmit state. A turbo decoder (210) for a receiver includes a soft decision decoder and a window error detector (214) coupled to the soft decision decoder. The window error detector generates a bad frame indication. The turbo decoder stops iterative processing of the data associated with a window when the window error detector detects that the window does not result in a bad frame indication.
