    摘要: A method and system for establishing a secure connection between stations are disclosed. The method includes that: 1) a switch device receives an inter-station key request packet sent by a first user terminal; 2) the switch device generates an inter-station key, constructs an inter-station key announcement packet and sends it to a second user terminal; 3) the switch device receives an inter-station key announcement response packet sent by the second user terminal; 4) the switch device constructs an inter-station key announcement response packet and sends it to the first user terminal; 5) the switch device receives an inter-station key announcement response packet sent by the first user terminal. The switch device establishes an inter-station key for the two stations which are connected to the switch device directly, by which the embodiments of the present invention ensure the confidentiality and integrality of user data between the stations.

    摘要: The quality and robustness of audio echo cancellation is enhanced by selectively applying glitch recovery processes based on a quality measurement of the relative offset between capture and render audio streams. For example, large and small glitch detection is enabled for low relative offset variance; large glitch detection is enabled in a medium range of relative offset variance; and neither enabled at high variance. Further, a fast glitch recovery process suspends updating the adaptive filter coefficients of the audio echo cancellation while buffers are re-aligned to recover from the glitch, so as to avoid resetting the adaptive filter. When clock drift exists between capture and render audio streams, a multi-step compensation method is applied to improve AEC output quality in case the drifting rate is low; and a resampler is used to compensate the drift in case the drifting rate is high. An anti-clipping process detects clipping of the signals, and also suspends adaptive filter updating during clipping.

    摘要: A communications device is presented for providing bi-directional audio communications between a near-end user and a far-end user via a bidirectional communications channel. The communications device includes an adaptive echo canceller receiving a near-end audio signal and a far-end audio signal and providing an echo-canceled near-end audio signal for transmission to the far-end user via the communications channel. The adaptive echo canceller includes a first bank of analysis filters for filtering the near-end audio signal, a second bank of analysis filters for filtering the far-end audio signal, and a bank of synthesis filters for filtering sub-band echo-canceled signals generated within the adaptive echo canceller. The first and second filter banks have a frequency response optimized to reduce echo residual gain.
