 - **redundant bits** are added for *error detection* and *error correction*;
 - some special algorithms (<u>coding schemes</u>) are used for this.

 The fact how "further" a certain algorithm divides the code words among themselves, and determines how strongly it protects the signal from noise [1, p.23].

 In the case of binary codes, the minimum distance between all existing code words is called **Hamming distance** and is usually denoted **dmin**:

 ## Net bit rate
 Redundancy of the channel coding schemes influences (decreases) bit rate. Actually, it is the cost for the noiseless increasing.
 [**Net bit rate**](https://en.wikipedia.org/wiki/Bit_rate#Information_rate) concept is usually used:

 To change the code rate (k/n) of the block code dimensions of the Generator matrix can be changed:

 To change the coderate of the continuous code, e.g. convolutional code, **puncturing** procedure is frequently used:
