Problems solved by technology

[0005] Since the achievable rate of short-distance DSL technology line is very high, even up to 1Gbps, and the average rate of users is much lower than this value, in traditional DSL technology, when the user rate is low, idle information will be filled in the sending frame, The signal keeps being sent on the line. At this time, most of the symbols in the frame do not carry user data and carry idle information, but the symbols carrying idle information also consume digital front end (DFE), analog front end ( Analog front end, AFE) and line driver (line Driver, LD) power consumption, the receiver also consumes power because it needs to process these symbols

Embodiment 1

[0044] The digital subscriber line signal processing method provided in this embodiment includes:

[0045] The transceiver carries the data to be sent on the symbol of the frame to be sent;

[0046] According to the size of the data to be sent and the data capacity of the frame to be sent, the transceiver estimates that in the symbols of the frame to be sent this time, the filled bit information is the number of symbols that are all idle information, that is, the number of remaining symbols, such as K symbols, It can also be said to be K remaining symbols;

[0047] The transceiver sets the signal transmission power of all K symbols carrying idle information to 0. Since the information carried by the symbols carrying idle information is empty, setting the signal transmission power to 0 does not affect the communication quality of the data, and reduces the The power consumption of the transmitted signal;

[0048] If K is not 0, the transceiver adds quantity information K to th...

Embodiment 2

[0050] The digital subscriber line signal processing method provided in this embodiment includes:

[0051] A certain transceiver carries the data to be sent on the symbol of the frame to be sent;

[0052] The transceiver estimates, according to the size of the data to be sent and the data capacity of the frame to be sent, the number of symbols in which the filled bit information is all idle information, such as K symbols, in the symbols of the frame to be sent this time;

[0053] The transceiver replaces the K symbols whose filled bit information is all idle information with idle symbols. The idle symbols are a specific symbol pre-agreed by both parties of the transceiver, which can reduce the generation of K symbols carrying idle information by the transceiver. DFE handles power consumption. On the receiving side receiving the frame sent by the transceiver, the idle symbol can be directly discarded without processing, thereby further reducing power consumption;

[0054] If K...

Embodiment 3

[0057] This embodiment combines the above-mentioned embodiment 1 and embodiment 2. The difference from the above-mentioned embodiment 1 and embodiment 2 is that the bit information filled by the transceiver is all part of the K symbols of the idle information. The signal transmission power is set to 0, and another part of symbols are replaced with idle symbols in the second embodiment. Similarly, the transceiver adds quantity information K to the operation and management symbol or the management message part of the frame to be sent, indicating that the number of symbols in which the filled bit information is all idle information in the frame is K, so that The receiver does not process the K symbols after receiving the indication, thereby further reducing the power consumption of signal processing.

Abstract

The embodiment of the invention refers to a digital subscriber line signal processing method and apparatus and a digital subscriber line system. The line signal processing method comprises the steps that frame symbols to be sent are employed to carry data to be sent; in the obtained frame to be sent of the data to be sent, the number of left symbols of the data to be sent is not carried; in the frame to be sent carried by the data to be sent, the number information of the left symbols are added, the frame carried with the data to be sent and added with the number information of the left symbols are sent. According to the embodiment, the frame to be sent is added with the number information of the left symbols of the data to be sent to make a receiver obtain the information that not carries the left symbols of the data to be sent and not process the left symbols, which can save signal processing power in a TDD DSL system, reduce power consumption and save energy for the TDD DSL system.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a digital subscriber line (Digital Subscriber Line, DSL) signal processing method, device and digital subscriber line system. Background technique [0002] The digital subscriber line technology is a high-speed transmission technology for data transmission through a telephone twisted pair, ie, an unshielded twisted pair (Unshielded Twist Pair, UTP). Currently available DSL technologies include Asymmetrical Digital Subscriber Line (ADSL), Very-high-bit-rate Digital Subscriber Line (VDSL), Integrated Services Digital Network, ISDN) subscriber digital line (ISDN Digital Subscriber Line, IDSL) and single-pair High-bit-rate Digital Subscriber Line (Single-pair High-bit-rate Digital Subscriber Line, SHDSL), etc. [0003] Among various digital subscriber line technologies (xDSL), in addition to DSL with baseband transmission such as IDSL and SHDSL, DSL with passband transmission us...
