2. Necessity of Error Correction

Transmitting data introduces many challenges. Among these challenges is the noise in a communication channel, which can result in errors in the transmission of bits. There are many types of noise.

Table 2.  Types of Noise
Noise Type Errors
Random or shot Uncorrelated errors
Crosstalk Correlated and uncorrelated errors
Return loss Mostly correlated errors
Insertion loss Uncorrelated errors
Decision Feedback Equalizer (DFE) error propagation Burst errors
