A parity bit is a bit that is added to a group of source bits to ensure that the number of set bits ( i. It is a very simple scheme that can be used to detect single or any other odd number ( i. , three, five, etc. In order for single- error correction to be possible, all valid codewords must be separated by. to detect double errors, you can send the single bit three times. Assignment: Single bit- error correction * * Motivation:.

after which you get to design your own error- correction scheme * to protect data stored in a. Forward Error Correction FEC Definition. to multiple destinations from a single source. Forward error coding is also. of generating bit error rate. Can someone explain, in their own words, what Double Bit Error Detection is and how to derive it?
