Sampling-based error code analysis method, error code analysis architecture and error code analyzer

The invention provides a sampling-based error code analysis method, an error code analysis architecture and an error code analyzer. The method comprises the following steps: acquiring a transmission rate of transmission data; according to the obtained transmission rate, selecting a corresponding working mode to sample the transmission data to obtain sampling data; the higher the transmission rate is, the larger the sampling bit interval of the corresponding working mode is; wherein the working modes comprise N working modes, and the sampling bit interval of the transmission data is sequentially increased by 2i times from the first working mode to the Nth working mode; wherein N is a positive integer, and N is greater than 1; i is a positive integer and is greater than or equal to 1; and according to the sampling property of the discrete sequence, the obtained sampling data can restore the transmission data, so that error code analysis on the transmission data with a high transmission rate at a low analysis ra
