WebHamming Codes are linear block codes designed to detect and correct errors introduced in message bits transmitted from an end to another through a communication channel. These are single error-correcting codes that offer ease in encoding and decoding. Hamming Code falls under the category of error correction coding and is a type of cyclic code. http://euler.ecs.umass.edu/ece655/hwks/hw2.pdf dols east riding
