摘要： An electronic device for reconstructing a lost packet in a Sub-Band Coding (SBC) decoder is described. The electronic device includes a processor and instructions stored in memory. The electronic device detects a lost packet, obtains a zero-input response of a synthesis filter bank and obtains a coarse pitch estimate. The electronic device also obtains a fine pitch estimate based on the zero-input response and the coarse pitch estimate. The electronic device selects a last pitch period based on the fine pitch estimate and uses samples from the last pitch period for the lost packet.

摘要： In general, techniques are described for performing majority vote error correction techniques. In operation, a communication device comprising a control unit implements the majority vote error correction techniques. The control unit includes a link management module to request a first retransmission of a first communication received over a wireless communication medium in response to detecting a first uncorrectable error in the first communication, requests a second retransmission of the first communication in response to detecting a second uncorrectable error in a second communication received in response to the first retransmission request and receives a third communication in response to the second retransmission. The control unit also includes a majority vote module to, in response to detecting a third uncorrectable error in the third communication, perform a bit-wise majority vote on corresponding bits of the first, second and third communications to generate an error-corrected communication.

摘要： Encoder-assisted frame loss concealment (FLC) techniques for decoding audio signals are described. A decoder may discard an erroneous frame of an audio signal and may implement the encoder-assisted FLC techniques in order to accurately conceal the discarded frame based on neighboring frames and side-information transmitted from the encoder. The encoder-assisted FLC techniques include estimating magnitudes of frequency-domain data for the frame based on frequency-domain data of neighboring frames, and estimating signs of the frequency-domain data based on a subset of signs transmitted from the encoder as side-information. Frequency-domain data for a frame of an audio signal includes tonal components and noise components. Signs estimated from a random signal may be substantially accurate for the noise components of the frequency-domain data. However, to achieve highly accurate sign estimation for the tonal components, the encoder transmits signs for the tonal components of the frequency-domain data as side-information.
摘要翻译：描述了用于解码音频信号的编码器辅助帧丢失隐藏（FLC）技术。解码器可以丢弃音频信号的错误帧，并且可以实现编码器辅助的FLC技术，以便基于相邻帧和从编码器发送的侧信息来准确地隐藏丢弃的帧。编码器辅助FLC技术包括基于相邻帧的频域数据来估计帧的频域数据的幅度，并且基于从编码器发送的符号子集估计频域数据的符号作为侧信息。音频信号的帧的频域数据包括音调分量和噪声分量。从随机信号估计的符号对于频域数据的噪声分量可能是基本准确的。然而，为了实现对音调分量的高度准确的符号估计，编码器将用于频域数据的音调分量的符号作为侧信息发送。

摘要： An original loudness level of an audio signal is maintained for a mobile device while maintaining sound quality as good as possible and protecting the loudspeaker used in the mobile device. The loudness of an audio ( e.g. , speech) signal may be maximized while controlling the excursion of the diaphragm of the loudspeaker (in a mobile device) to stay within the allowed range. In an implementation, the peak excursion is predicted ( e.g. , estimated) using the input signal and an excursion transfer function. The signal may then be modified to limit the excursion and to maximize loudness.

摘要： Disclosed is a negative C-type retardation compensator for a liquid crystal display. The negative C-type retardation compensator for the liquid crystal display includes polyarylate having a thio group or a sulfur oxide group in a polymer main chain thereof. Accordingly, the retardation compensator has an absolute value of negative retardation that is larger in a thickness direction than a retardation compensator which includes polyarylate having no thio group or sulfur oxide group in a polymer main chain thereof even though the retardation compensator having the thio group or sulfur oxide group and the retardation compensator having no thio group or sulfur oxide group are the same as each other in thickness. Thereby, the negative C-type retardation compensator for liquid crystal displays is capable of being desirably applied to the liquid crystal displays.
