    摘要: Embodiments of a method and apparatus for selecting coefficients of a non-linear filter are disclosed. The non-linear filter receives a transmit signal and generates a non-linear replica signal of a transmit DAC of a transceiver. The method include applying a plurality of periodic test pattern signals to inputs of the transmit DAC, wherein the periodic test pattern signals include a stream of symbols. Receive symbols are collected at an output of a receiver ADC of the transceiver resulting from the plurality of periodic test pattern signals. A non-linear map is generated that provides a value for each of n consecutive symbols input to the transmit DAC. Coefficients of the non-linear filter are selected based on the non-linear map.

    摘要: Embodiments of a method and apparatus for decoding an Ethernet signal are disclosed. The method includes receiving an Ethernet bit stream. The bit stream is at least one of low-complexity decoded or high-complexity decoded. If the bit stream fails a low-complexity decoding test, then the bit stream is high-complexity decoded. The low-complexity decoding and high complexity decoding are iteratively repeated until the bit stream passes the low-complexity decoding test.

    摘要: Embodiments of a method and apparatus for reducing non-linear transmit signal components of a receive signal of a transceiver signal are disclosed. The method includes the transceiver simultaneously transmitting a transmit signal, and receiving the receive signal. A non-linear replica signal of non-linear transmission signal components that are created in the transceiver by a transmit signal DAC, and imposed onto the receive signal, is generated. The non-linear replica signal is subtracted from the received signal reducing the non-linear transmission signal components imposed onto the receive signal.

    摘要: A device and method of high-speed transmission is disclosed. The method includes computing a signal quality of a received signal, the received signal being transmitted with a modulation order required by a default transmission modulation format. The signal quality is compared with a signal quality threshold required of the default transmission modulation format. If the signal quality is below the signal quality threshold, an indication of a level of signal quality failure is provided to a transmitter. The transmitter sets a number of un-coded bits within the transmission signal based upon the level of signal quality failure.

    摘要: A wireless link between a first transmitter and a first receiver in a multiple access communications system is evaluated by receiving, at the first transmitter, information that is intended for a second receiver and that is transmitted in a second transmission mode that is different from the current transmission mode and obtaining an error measure for the information that is received at the first receiver and intended for the second receiver. The obtained error measure is then used to determine if the second transmission mode is an acceptable transmission mode. In an embodiment, if the second transmission mode is determined to be acceptable, then the current transmission mode of the first receiver can be replaced by the second transmission mode. In an embodiment, the current transmission mode is replaced by the second transmission mode only if the second transmission mode is a “higher” transmission mode than the current transmission.
