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.
