    摘要: A wireless communication system comprises a sampling module that samples a first portion and a second portion of a channel using a sampling time. A correlator module selectively correlates the first portion and the second portion, generates correlation samples, and calculates an offset based on the correlation samples. A timing module selectively adjusts the sampling time based on the offset.

    摘要: A method of generating a data constellation at a client modem is provided whereby an optimum distance between data constellation data points may be calculated for a predetermined, acceptable error probability. An iterative process may be carried out using proposed data constellations which may be used to provide factors for calculating corrected constellations. Once a constellation is generated to satisfy the required probability of error, the constellation may be re-evaluated using CRC errors and detected noise variance at the client modem. Based upon predetermined levels of noise variance and CRC error, the constellation may be regenerated to operate at either a higher bit rate or a lower bit rate.

    摘要: A Digital Impairment Learning sequence which is designed for providing reliable estimate of digital impairments such as PAD, RBS, and CODEC type in the presence of analog impairments such as IMD, noise and changing line conditions. This estimate is used to derive optimum transmit symbol constellations for a modem connected digitally to a trunk so as to maximize its data transmission rate.
