Simulating a channel that generates random errors in a data packet. Generalize Example 16.68 to simulate a channel that produces random errors to a 4 × 4 data packet. Save the data packet on the disk.

Example 16.68

Simulating random errors in a block code

Figure 16.67 shows a Matlab script that reads the 3 × 3 block code generated with Example 16.67, introduces random errors, and saves the block code on the disk that acts as a transmission channel.

Example 16.67

Forming a data block code with parity and LRC

Figure 16.66 shows a Matlab script that simulates a transmitter that forms a simple 2 × 2 data block with parity and a LRC to form a 3 × 3 block code and saves it on the disk that acts as a transmitter.
