, Note
Data can be corrupted
during transmission.
Some applications require that
errors be detected and corrected.
10.2
, 10-1 INTRODUCTION
Let us first discuss some issues related, directly or
indirectly, to error detection and correction.
Topics discussed in this section:
Types of Errors
Redundancy
Detection Versus Correction
Forward Error Correction Versus Retransmission
Coding
Modular Arithmetic

, Note
In a single-bit error, only 1 bit in the data
unit has changed.
