An adaptive multi-rate data transmission and reception method and device

Abstract

The invention discloses a self-adaption multi-rate data transmitting and receiving method and device. The method comprises the steps that a transmitting end acquires groups of user data, and respectively generates control and state indicating signals corresponding to each group of user data according to the data transmitting state of the transmitting end the length of each group of user data; the transmitting end respectively determines the length of an idle character corresponding to each group of user data according to the transmitting rate of each group of user data and the work rate of the current parallel-serial and series-parallel converter SERDES of the transmitting end; the transmitting end encapsulates a data frame according to groups of user data, the length of the idle characters which are one-to-one corresponding to groups of user data, and each corresponding control and state indicating signal; and the transmitting end transmits the acquired data frame to a receiving end, so as to solve the problems of complex SERDES serial transmitting protocol, difficult realization, high cost and relatively fixed SERDES serial transmitting rate in prior art.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an adaptive multi-rate data sending and receiving method and device. Background technique [0002] With the development of the times and the advancement of science and technology, the communication field is gradually developing from narrowband to broadband. The continuous improvement of communication requirements has led to an increase in bandwidth requirements and higher requirements for data transmission rates. [0003] The traditional data transmission method adopts parallel transmission, and the traditional method to increase the data transmission bandwidth is to realize by increasing the working frequency of the data and increasing the bit width of the data. However, this method will lead to a double increase in the number of chip pins used, a sharp increase in the interconnection lines between chips, and a large number of connections will bring great difficulties to ...
