摘要： The present invention discloses a base of a cordless digital telephone set and a cordless digital telephone set, and relates to the field of digital communications. In the base of a cordless digital telephone set, a subscriber circuit module and a Bluetooth module can establish, under control of a main control module, a communications channel for direct interconnection, thereby reducing workload of the main control module, and optimizing a transmission path of voice data. The base of a cordless digital telephone set in embodiments of the present invention includes a switch module. When receiving a first control signal that is sent by the main control module, the switch module connects a communication data output pin of the subscriber line interface circuit module to a communication data input pin of the Bluetooth module; and connects a communication data input pin of the subscriber line interface circuit module to a communication data output pin of the Bluetooth module.

摘要： In a communication system, a precoder is coupled between first and second portions of each of a plurality of transmitters. The precoder is configured to receive an adaptive index representation of a scaled signal associated with the first portion of a first one of the transmitters, and to process the adaptive index representation using an adjusted precoder coefficient to generate a precompensation signal. The precompensation signal is supplied from the precoder to the second portion of a second one of the transmitters for use in precompensation of at least one signal to be transmitted by the second transmitter.
