Embodiment Construction

[0063] In the data transmission network provided by the embodiment of the present invention, the sending end can modulate the data before sending the data to the receiving end. Such as figure 1 As shown, figure 1 This is a schematic structural diagram of the PAM-M circuit provided in this embodiment. The data transmitted on m links are input to the PAM-M circuit for modulation. Among them, the PAM-M circuit is used to modulate the data transmitted on the kth link among the m links to 2 k-1 The corresponding level. k=1,...,m.

[0064] At the transmitting end, m links are respectively connected to the PAM-M circuit, and the m links send data to the PAM-M circuit for modulation. Among them, the data transmitted on the kth link in the m links is modulated to 2 k-1 The corresponding level. And at a certain time, the kth link only sends one data unit to the PAM-M circuit for modulation. k=1,...,m. The data unit can be a bit or a symbol. Among them, one symbol includes at least ...

Abstract

The embodiment of the present invention discloses a data processing method and a data processing device. The method includes: an encoding circuit respectively receives m data streams through m receiving ports, and the m data streams include m×m data units. m×m data units form an m-order matrix A; the encoding circuit keeps the position of one element on each row in the matrix A unchanged and moves the remaining m-1 elements to the remaining m-1 elements respectively Rows to form an m-order matrix B, and each element in the remaining m-1 elements is moved before and after the number of columns in the matrix A and the number of columns in the matrix B are equal; The encoding circuit sends the m×m elements in the matrix B to m different levels of the PAM circuit through m sending ports for modulation.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a data processing method and data processing device. Background technique [0002] A commonly used modulation technique in Ethernet is pulse amplitude modulation (English: pulse amplitude modulation, abbreviation: PAM). The following takes PAM-4 circuit as an example to describe the working flow of the PAM circuit. PAM-4 circuit receives the data sent by link 0 and the data sent by link 1, and modulates the data sent by link 0 to 2 0 At the corresponding level, modulate the data sent by link 1 to 2 1 The corresponding level. At a certain time, the data sent by each link is 0 or 1. Therefore, the PAM-4 circuit modulates the four types of data 00, 01, 10, and 11 sent by link 0 and link 1 to obtain pulse signals with amplitudes of 0, 1, 2 and 3 respectively. The PAM-4 circuit sends the pulse signal to the receiving end. After receiving the pulse signal, the receiving end d...
