[′par·əd·ē ‚bit]
(communications)
An additional nondata bit that is attached to a set of data bits to check their validity; it is set so that the sum of one-bits in the augmented set is always odd or always even.

Then we use the data bit extrinsic information [L.sup.i.sup.e2,k] of decoder 2 and the parity bit extrinsic information [L.sup.p.sup.e1,k] or [L.sup.p.sup.e2,k] to calculate the desired information of [s.sub.k] which is soft decision detected (44) and final output detection of data dk which is hard decision detected (45) using the foll owing equation,

Parity bit checking was widely used for its simplicity and ease of implementation, but is by no means a foolproof means of error detection.
Using a simplistic example: 10011100 is transferred (where the last bit is a parity bit using an even scheme) and received as 11111100.
