Abstract
The system may include a plurality of communication connections. A number of transmitters may transmit a signal to a number of receivers, the respective transmitter is adapted to convey transmit signal power to more than one receiver in the number of receivers. A process may adapt the allocation of power of a transmission to the receivers for signal transmission to more than one receiver.
Claims18
A communication system with a plurality of electronic communication connections, comprising:
- a distribution point, comprising components that perform vector precoding and vector transmission PSD;
- a crosstalk channel;
- a plurality of CPE devices, comprising components that perform vector equalization;
- a plurality of lines serving CPE devices, the plurality of lines being bonded;
- wherein the system is configured to allow joint optimization of a DP precoder and a CPE equalizer, or of a DP equalizer and a CPE decoder;
- and
- wherein the distribution point controls all elements in the system, and operates the system to maximize the communication capabilities with the lowest possible system resources.
A CPE device for use in a communication system, the CPE device adapted for communication connection with a first plurality of transmitters provided in a distribution point, the CPE device comprising:
- a first plurality of receivers;
- and
- a vector equalizer adapted to cancel crosstalk.
A method for improving spectrum utilization in a communication system with a plurality of electronic communication connections, the method comprising:
- each of a number of transmitters transmitting a signal to a number of receivers;
- conveying at least part of the power of each transmission to each of two or more receivers;
- and
- modifying the allocation of power of a transmission to the receivers such that the spectrum utilization is greater than if each receiver were to receive the same transmission power from each transmission from each transmitter.
A distribution point for use in a communication system, the distribution point comprising:
- a first plurality of transmitters adapted for communication connection to a second plurality of receivers, and
- a precoder configured to allocate transmission power of at least one of the transmitters to at least two of the receivers, the precoder being configured to allocate the transmission power for multipath signal transmission from the transmitter to the at least two receivers.
