摘要： An upstream transceiver, coupled to an upstream end of a long haul, single digital subscriber loop of an extended range asymmetrical digital subscriber line communication system, nullspoofsnull a (co-located) digital subscriber line access multiplexer to reduce its downstream data rate over a short haul loop to the upstream transceiver. The reduced downstream data rate is compatible with the data rate that can be supported by the long haul loop and also accommodates an auxiliary (64K) POTS channel thereover. The reduced data rate may be derived by preliminary signal quality measurements upon the long communication loop conducted between the upstream transceiver and a downstream transceiver coupled to a remote end of the long haul loop.

摘要： S/P transform section 101a transforms transmission data A from serial data into parallel data, and outputs the parallel data to 16 QAM mapping section 102 as data to be mapped onto bits (S0 and S1) with relatively high quality. S/P transform section 101b transforms transmission data B from serial data into parallel data, and outputs the parallel data to 16 QAM mapping section 102 as data to be mapped onto bits (S2 and S3) with relatively low quality. 16 QAM mapping section 102 performs mapping on transmission data A and B on the signal space diagram of 16 QAM by Gray Coding. Then, transmission data A and B undergoes digital modulation, and is transmitted to a communicating party via antenna 105.

摘要： A method for adaptive-rate communication includes setting a first target signal margin with respect to an actual noise level and a second target signal margin with respect to a predetermined noise level. The actual noise level is measured at a receiver on a communication channel between a transmitter and the receiver. A transmission rate is selected at which to transmit a signal on the channel such that for the selected transmission rate, a first signal-to-noise ratio (SNR) of the signal relative to the measured actual noise level is greater than a baseline SNR level by at least the first target signal margin, and a second SNR of the signal relative to the predetermined noise level is greater than the baseline SNR by at least the second target signal margin.

摘要： A modulation/demodulation device capable of operating with several types of modulation using different carrier frequencies may include a modulator which modulates at least one signal by a signal of a predetermined duration and representative of a binary information supplied by a microprocessor. The device may also include a demodulator which demodulates the modulated signals arriving from a remote site. This may be done by determining the type of modulation of the received signals and their carrier frequency (or frequencies), supplying signals from an analysis of the signals received according to the determined type of modulation, and detecting the signals of determined duration representative of binary information to make them accessible to the microprocessor.
