Abstract

An information processing apparatus includes: a decoding module, configured to receive M first codewords from at least one peer device, where each first codeword includes first service data with a K-unit length and an error correction code with an R-unit length, where the decoding module is further configured to decode the M first codewords to obtain M second codewords, where a length of each second codeword is a sum of the K-unit length and the R-unit length, each second codeword includes second service data with the K-unit length and error correction information, the second service data is error-corrected first service data; and a classification and statistics collection module, configured to determine a bit error rate of the first service data based on the error correction information.

Dependent claims

A method, comprising:

receiving M first codewords from at least one peer device, wherein each first codeword of the M first codewords comprises first service data with a K-unit length and an error correction code with an R-unit length, and M, K, and R are all integers greater than or equal to 1;
and
decoding the M first codewords to obtain M second codewords, wherein a length of each second codeword is a sum of the K-unit length and the R-unit length of the corresponding first codeword, each second codeword comprises second service data with the K-unit length of the corresponding first codeword and error correction information of the corresponding first codeword, the second service data is error-corrected first service data of the corresponding first codeword, and the error correction information is error statistics information obtained after error correction is performed on the first service data with the K-unit length of the corresponding first codeword based on the error correction code with the R-unit length of the corresponding first codeword.

A method, comprising:

receiving M second codewords, wherein a length of each second codeword of the M second codewords is a sum of a K-unit length and an R-unit length, each second codeword comprises second service data with the K-unit length of the corresponding second codeword and error correction information, the second service data of each second codeword is error-corrected first service data of a corresponding first codeword of M first codewords, the error correction information of each second codeword is error statistics information obtained after error correction is performed on first service data with the K-unit length based on an error correction code with the R-unit length in a corresponding first codeword of the M first codewords, and M, K, and R are all integers greater than or equal to 1;
and
determining a bit error rate of the first service data of each first codeword based on the error correction information of each second codeword.

An apparatus, comprising:

a receiver, configured to receive M second codewords sent by a second apparatus, wherein a length of each second codeword of the M second codewords is a sum of a K-unit length and an R-unit length of the corresponding second codeword, each second codeword comprises second service data with the K-unit length of the corresponding second codeword and error correction information, the second service data of each second codeword is error-corrected first service data of a corresponding first codeword of M first codewords, the error correction information of each second codeword is error statistics information obtained after error correction is performed on first service data with the K-unit length based on an error correction code with the R-unit length in a corresponding first codeword of the M first codewords, and M, K, and R are all integers greater than or equal to 1;
at least one processor;
and
a non-transitory computer readable storage medium storing a program that is executable by the at least one processor, the program including instructions to:
determine a bit error rate of the first service data of each first codeword based on the error correction information of each second codeword.
