| 21. | Each one of them corresponds to a codeword.
|
| 22. | Generally, N is length of the codeword.
|
| 23. | The caller, who gave no codeword, warned of car bombs in seven locations.
|
| 24. | The decoders described below use the BCH view of the codeword as sequence of coefficients.
|
| 25. | Consider a codeword of length n sent through the AWGN channel with noise level N.
|
| 26. | There are three distinct bar & ndash; space patterns used to represent each codeword.
|
| 27. | Consequently, the code can detect and correct up to 2 errors in a codeword.
|
| 28. | Each data codeword carries 20 bits of data ( bits 30 through to 11 ).
|
| 29. | So, their difference is a codeword.
|
| 30. | Then no nonzero burst of length \ leqslant 2 \ ell can be a codeword.
