Who is proficient in the content of computer check codes? The most important ones are horizontal parity check codes and vertical parity check codes. Can you tell me some better examples?

. Characteristics and coding rules of vertical parity check

Features: Vertical parity check is also called vertical parity check. It can detect all odd errors in each column, but An even number of errors cannot be detected. Therefore, the missed detection rate of errors is close to 1/2.

2. Characteristics and encoding of horizontal parity check Rules

Features: Horizontal parity check is also called horizontal parity check. It can not only detect an odd number of errors on the same bit in each segment, but also detect all bursts with burst length <= p. Send an error. Its miss detection rate is lower than the vertical parity check method, but when implementing horizontal parity check, a data buffer must be used.
