Embodiment Construction

[0028] Various embodiments of the communication device of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Figure 2A A schematic diagram of a communication device according to an embodiment of the present invention is shown. The communication device 100 is applicable to figure 1 The receiving circuit Rx. The communication device 100 includes a calculator 110, a digital / analog converter 120, a level determination module 130, an analog front-end device (AnalogFront-End) 140, an analog / digital converter (AnalogtoDigitalConvertor, ADC) 150, and a backend elimination module 160 .

[0030] The communication device 100 receives a received signal SRX. In one embodiment, the received signal SRX may include the signal transmitted by the remote communication device, and noise components of echo (Echo) and crosstalk (Near-End CrossTalk, NEXT) carried by the signal.

[0031] The calculator 110 is used for subtracting a puls...

Abstract

The invention disclosed a communication device and its reception method.The communication device contains a digital / simulation converter, one -inverted response filter circuit, and an analog / digital converter.Digital / analog converters receive a first digital signal to generate an analog signal in a vein form.The negative response filter circuit receives a difference signal generated by the analog signal of a receiving signal and the pulse form, and adjusts the response of the reverse response filter circuit to generate a post -adjustment signal.The analog / digital converter simulates the adjustment signal to the digital conversion to generate a second digital signal.

Description

technical field [0001] The invention relates to a communication device, in particular to a communication device capable of eliminating near-end interference and dynamically adjusting high-frequency response. Background technique [0002] figure 1 A schematic diagram showing a general communication device. The communication device 10 includes a transmission medium 11, a hybrid circuit (Hybrid Circuit) 12, a local transmitting circuit Tx, and a local receiving circuit Rx. Through the transmission medium 11, the communication device 10 and the remote communication device can perform signal transmission and reception. Generally, the local transmission circuit Tx includes a digital / analog converter (not shown), which converts the signal from digital to analog to generate a transmission signal STX, and outputs it through the hybrid circuit 12 and the transmission medium 11 . The local receiving circuit Rx includes an analog / digital converter (not shown), which converts the rece...
