Abstract

The embodiment of the invention discloses an information processing method and device, and the device comprises a decoding module which is used for receiving M first code words from at least one opposite terminal device, wherein each first code word comprises first business data of K unit lengths and error correction codes of R unit lengths; the decoding module is further used for decoding the M first code words to obtain M second code words, the length of each second code word is the sum of K unit lengths and R unit lengths, each second code word comprises second service data of the K unit lengths and error correction information, the second service data is the first service data after error correction, the error correction information is error statistical information obtained by performing error correction on the first service data with the K unit lengths according to the error correction codes with the R unit lengths; and the classification statistics module is used for determining the error rate of the first service data according to the error correction information. By adopting the embodiment of the invention, the data processing efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an information processing method and device. Background technique [0002] In a digital communication system, due to factors such as noise and crosstalk introduced in the transmission channel, the signal received by the receiving device is distorted, which in turn leads to system bit errors. In order to avoid or reduce system bit errors, forward error correction (forward error correction, FEC) is widely used in digital transmission systems. However, due to size, power consumption or cost constraints, when the FEC decoding module and the classification identification module belong to two different components, the receiving device cannot determine the error correction information corresponding to the service data of each peer device , affecting the transmission efficiency of error correction information, resulting in low data processing efficiency.
