Codeword in a sentence

A particular codeword of any line code can either have no disparity (the average weight of the codeword is zero), negative disparity (the average weight of the codeword is negative), or positive disparity (the average weight of the codeword is positive).

In a paired disparity code, every codeword that averages to a negative level (negative disparity) is paired with some other codeword that averages to a positive level (positive disparity).

Once a polynomial is determined, then any errors in the codeword can be corrected, by recalculating the corresponding codeword values.

At the White House, copies of documents marked “classified” or the even more secret “compartmentalized” or “codeword” can circulate among officials there with proper clearance.

Although the codewords as produced by the above encoder schemes are not the same, there is a duality between the coefficients of polynomials and their values that would allow the same codeword to be considered as a set of coefficients or a set of values.

However, the practical decoders described below require a generator polynomial known to the decoder, and view a codeword as a set of coefficients.

If the system of equations can be solved, then the receiver knows how to modify the received word to get the most likely codeword that was sent.

In order to obtain a codeword of the Reed–Solomon code, the message is interpreted as the description of a polynomial p of degree less than k over the finite field F with q elements.

In the 1955 film The Dam Busters about the raid, the dog was portrayed in several scenes; his name and the codeword were mentioned several times.

In this example, the weighted average codeword length is 2.25 bits per symbol, only slightly larger than the calculated entropy of 2.205 bits per symbol.

In turn, the polynomial p is evaluated at n distinct points of the field F, and the sequence of values is the corresponding codeword.

It is generally beneficial to minimize the variance of codeword length.

Local decoding and testing of codes main Sometimes it is only necessary to decode single bits of the message, or to check whether a given signal is a codeword, and do so without looking at the entire signal.

Locally testable codes are error-correcting codes for which it can be checked probabilistically whether a signal is close to a codeword by only looking at a small number of positions of the signal.

Only the index of the codeword in the codebook is sent instead of the quantized values.

Reed & Solomon's original view: The codeword as a sequence of values There are different encoding procedures for the Reed–Solomon code, and thus, there are different ways to describe the set of all codewords.

Tapestry is a codeword for the activities by ships and aircraft that protect the United Kingdom's Sovereign Sea Areas, including the protection of fishing rights and oil and gas extraction.

The addition of the fourth row effectively computes the sum of all the codeword bits (data and parity) as the fourth parity bit.

The dog's name was used as a single codeword whose transmission conveyed that the Möhne dam had been breached.

The error values are then used to correct the received values at those locations to recover the original codeword.
