    摘要: A soft decision audio decoding system for preserving audio continuity in a digital wireless audio receiver is provided that deduces the likelihood of errors in a received digital signal, based on generated hard bits and soft bits. The soft bits may be utilized by a soft audio decoder to determine whether the digital signal should be decoded or muted. The soft bits may be generated based on the detected point and a detected noise power, or by using a soft-output Viterbi algorithm. The value of the soft bits may indicate confidence in the strength of the hard bit generation. The soft decision audio decoding system may infer errors and decode perceptually acceptable audio without requiring error detection, as in conventional systems, as well as have low latency and improved granularity.

    摘要: A flexible multi-channel diversity wireless audio receiver system for routing, processing, and combining multiple radio frequency (RF) signals containing audio signals received on respective antennas is provided. The wireless audio receiver system provides flexible routing of multiple RF signals in different selectable modes, and low latency uninterrupted reception of signals in harsh RF environments by combining multiple RF signals to maximize signal-to-noise ratio. The audio output may be generated in an uninterrupted fashion and mitigate multipath fading, interference, and asymmetrical noise issues. Received RF signals may also be cascaded by the wireless audio receiver system to allow daisy chaining.

    摘要: A soft decision audio decoding system for preserving audio continuity in a digital wireless audio receiver is provided that deduces the likelihood of errors in a received digital signal, based on generated hard bits and soft bits. The soft bits may be utilized by a soft audio decoder to determine whether the digital signal should be decoded or muted. The soft bits may be generated based on a degree of closeness of a detected phase trajectory to known legal phase trajectories determined from the running the phase trajectory through a soft-output Viterbi algorithm. The value of the soft bits may indicate confidence in the strength of the hard bit generation. The soft decision audio decoding system may infer errors and decode perceptually acceptable audio without requiring error detection, as in conventional systems, as well as have low latency and improved granularity.
