Abstract: Techniques for detecting received sequences when certain signaling characteristics (e.g., transport formats, rates) are not known a priori at the receiver. In one method, a sequence for a transmitted message is received, and a metric value is computed for each of a number of hypothesized messages corresponding to a number of hypotheses for the unknown signaling characteristic of the transmitted message. The metric value is computed based on a MAP metric derived to approximately maximize a joint a posteriori probability between the received sequence and the hypothesized messages. The hypothesized message having the best metric value is selected as the transmitted message. The specific form of the MAP metric is dependent on the particular signaling scheme used to map the message to its corresponding sequence, and may be used for blind transport format detection (BTFD) in a W-CDMA system and blind rate detection in an IS-95 CDMA system.

Abstract: Techniques for power control that avoids outer loop wind-up are disclosed. In one aspect, wind-up of a target power level is detected, and the target power level is modified in response. In another aspect, unwinding of the target power level is detected, after which the target power level is determined without considering wind-up. Various other aspects are also presented, including wind-up and unwinding detection procedures, and target power level modification procedures. These aspects have the benefit of reducing the time that transmit power exceeds that which is necessary, thus increasing system capacity and performance, and mitigating misallocation of system resources.

Abstract: This invention relates to mixtures of triazole compounds and in particular to the use of such mixtures in non-crystallising compositions. It relates to mixtures that are concentrated solutions and also to the use of the concentrated solutions in water diluted form. Furthermore, it relates to the use of such mixtures for agricultural or materials protection purposes and to the use of one triazole compound to prevent or delay crystallisation of a second triazole compound.

The spectrum of RF signals include a plurality of modulation techniques. The A/D converter is further adapted to sample the spectrum at a rate that is at least twice the frequency of the highest frequency signal that is contained within the spectrum. The digitized data stored in a memory device. A processor is adapted to process the digitized data.

Abstract: A method and system for synchronizing signals. First and second signals are sent (compressed or uncompressed) from a source to a receiving apparatus of a receiving system. The first signal has content of a first modality (e.g., audio) and the second signal has content of a second modality (e.g., video). The first and second signals are to be displayed on a display apparatus of the receiving system. The first and second signals have been time-synchronized at the source. If the first and second signals are not synchronized in time when received at the receiving apparatus, then the first and second signals may be time-synchronized at the receiving apparatus either manually or through timestamping of both signals at the source, in conjunction with use of a real-time clock at the receiving apparatus.

Abstract: Techniques to more efficiently control the transmit power for a data transmission that uses a number of formats (e.g., rates, transport formats). Different formats for a given data channel (e.g., transport channel) may require different target SNIRs to achieved a particular BLER. In one aspect, individual target BLER may be specified for each format of each data channel. In another aspect, various power control schemes are provided to achieve different target SNIRs for different formats. In a first power control scheme, multiple individual outer loops are maintained for multiple formats. For each format, its associated outer loop attempts to set the target SNIR such that the target BLER specified for that format is achieved. In a second power control scheme, multiple individual outer loops are maintained and the base station further applies different adjustments to the transmit power levels for different formats.

Abstract: The present invention provides an apparatus and method for switching between particular decoders within a plurality of decoders, each decoder adapted to decode bit streams having a unique format. The apparatus comprises format detectors which output format indicators based on information from the bit stream. Logic responsive to the format detector output may determine a particular decoder among the plurality of decoders. The particular decoder determined by the logic decodes the formatted bit stream. At least one switch, responsive to the determination of the logic, connects the formatted bit stream to the particular decoder. The format detectors detect at least one of the frame information, or start code, the packet header information, and the code word values in a portion of a coded content of the bit stream, wherein the code word values, derivatives thereof, or a pattern of code word values, are unique to the bit stream format.

Abstract: A trellis decoder determines the most likely transmitted phase in response to previously requested phase adjustments and observed transmitted symbols. Maximum a posteriori (MAP) decoding also may be used. Alternatively, the identified likely transmitted phase is used for data demodulation. This and related features have the benefit of decreasing the effect of phase discrepancies introduced by erroneous reception of phase adjustment information, resulting in improved error rates, and a corresponding increase in system capacity, data throughput, or both.
