摘要： In one embodiment, an algorithm dynamically selects a method for reducing distortion in a multi-carrier modulated signal, such as an orthogonal frequency division multiplexing (OFDM) signal. The algorithm directs a transmitter to transmit peak-to-average power ratio (PAPR)-reduction signals over reserved tones (i.e., frequencies) if reserved tones are available. If reserved tones are not available, then the algorithm directs the transmitter to transmit PAPR-reduction symbols over free tones if free tones are available. If the free tones for this transmitter are used by adjacent transmitters, then interference-reduction techniques may be used to reduce interference with the adjacent transmitters. If reserved tones and free tones are not available, then the transmitter may use an alternative method to reduce distortion, such as successive clipping and filtering. In another embodiment, the transmitter may transmit PAPR-reduction symbols over both free and reserved tones, if available.
摘要翻译：在一个实施例中，算法动态地选择减少诸如正交频分复用（OFDM）信号的多载波调制信号中的失真的方法。如果保留的音调可用，该算法指示发射机在保留的音调（即，频率）上发射峰均功率比（PAPR） - 减小信号。如果保留的音调不可用，则如果可用音调可用，则算法指示发射机在自由音调上发送PAPR减少符号。如果该发射机的自由音由相邻发射机使用，则可以使用干扰减少技术来减少与相邻发射机的干扰。如果保留的音调和自由音调不可用，则发射机可以使用替代方法来减少失真，例如连续的削波和滤波。在另一个实施例中，如果可用，发射机可以在自由和保留的音调两者之间传送PAPR减少符号。

摘要： In one embodiment, the presence of double talk (DT) is detected in a telecommunications network having a near-end user and a far-end user. The energies of both (1) a signal received from the far-end user by the near-end user and (2) a signal to be communicated from the near-end user to the far-end user are computed. An echo return loss (ERL) estimate is calculated based on the energy calculations, and a preliminary decision is made as to whether DT is present based on the ERL estimate and the energy calculations. If DT is detected, then a counter is set to a hangover value. If DT is not detected, then the counter is reduced. This process is repeated, and, for each iteration, a final decision as to whether DT is present is made based on the counter value.

摘要： The invention provides a communication protocol and serial interface having an approximately fixed interface clock and capable of accommodating a variety of communication rates. The interface employs a variable-length frame that may be expanded or reduced to obtain a desired communication rate, even though the interface clock rate is held approximately constant. The invention further provides a method for designing an agile barrier interface. In particular, the barrier clock rate is preferably selected to be an approximate common multiple of the various communication rates that the barrier interface must handle. The frame length corresponding to each communication rate may then be obtained by dividing the barrier clock rate by the ΣΔ rate. Finally, the invention provides an agile barrier capable of communicating data across a serial interface at a variety of data rates and at an approximately fixed interface clock rate.

摘要： An integrated circuit having a monitor circuit for monitoring timing in a critical path having a target timing margin is disclosed. The monitor circuit has two shift registers, one of which includes a delay element that applies a delay value to a received signal. The inputs to the two shift registers form a signal input node capable of receiving an input signal. The monitor circuit also has a logic gate having an output and at least two inputs, each input connected to a corresponding one of the outputs of the two shift registers. The output of the logic gate indicates whether the target timing margin is satisfied or not satisfied.
