    摘要: A method and system that combines voice recognition engines and resolves any differences between the results of individual voice recognition engines. A speaker independent (SI) Hidden Markov Model (HMM) engine, a speaker independent Dynamic Time Warping (DTW-SI) engine and a speaker dependent Dynamic Time Warping (DTW-SD) engine are combined. Combining and resolving the results of these engines results in a system with better recognition accuracy and lower rejection rates than using the results of only one engine.

    摘要: Techniques for improved margin control in a data communication system are disclosed. In one aspect, margin is adjusted in response to a first subpacket error rate. In another aspect, margin is further adjusted in response to an overall packet error rate. In yet another aspect, the first subpacket error rate is adjusted in response to an overall packet error rate. Various other aspects are also presented. These aspects have the benefit of responsive margin control when the overall packet error rate is relatively low, resulting in improved data throughput and increased system capacity.

    摘要: Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.

    摘要: Methods and apparatus are presented to select optimal transmission formats for transmissions to a single user or simultaneous transmissions to multiple users. Priority information and channel state information associated with each user are used to determine the optimal transmit formats. In particular, said formation is used to maximize a given revenue function that enhances system throughput while maintaining fairness among users. Once transmit formats are determined, any unallocated system resources, such as unused Walsh codes or transmission power, can be evenly or proportionately distributed among the users.

    摘要: Methods and apparatus are presented for improving the feedback of channel information to a serving base station, which allows a reduction in the reverse link load while allowing the base station to improve the forward link data throughput. Over a channel quality indicator channel, three subchannels are generated; the re-synch subchannel, the differential feedback subchannel, and the transition indicator subchannel. The information carried on each subchannel can be used separately or together by a base station to selectively update internal registers storing channel conditions. The channel conditions are used to determine transmission formats, power levels, and data rates of forward link transmissions.

    摘要: A method for scheduling packet data transmissions in a wireless communication system wherein a per-user Priority Function (PF) is calculated based on the channel condition and throughput for each user. In one embodiment, the system supports retransmission of data packets and sub-packets, wherein the retransmission information is used to schedule data transmissions. In another embodiment, at each time interval the system updates the priority factor for the user having the highest priority factor in the previous time interval. The priority factors of the other users remain unchanged.
