Used in satellite and mobile communications (3G/4G) to correct errors in real-time.
While source coding removes redundancy, to help detect and correct errors caused by noise. Common Coding Techniques:
Error correction ensures your files remain uncorrupted even if parts of the physical disk degrade. Seeking the PDF? information theory and coding by giridhar pdf
Every communication channel (fiber optic, wireless, copper) has a limit on how much data it can carry. This is known as the .
NASA uses these coding principles to receive clear images from Mars despite immense distances and interference. Used in satellite and mobile communications (3G/4G) to
The logic behind GIF and ZIP files, which builds a dictionary of recurring patterns. 3. Channel Capacity and Noise
A more common optimal prefix code used for lossless data compression. It ensures that frequently occurring characters have shorter codes, while rare characters have longer ones. Seeking the PDF
In the digital age, every bit of data—from a simple text message to a 4K video stream—relies on the principles of . This field, pioneered by Claude Shannon in 1948, determines how we measure information, how we compress it, and how we protect it from noise during transmission. 1. What is Information Theory?
Widely used in networking (like Ethernet) to detect data corruption.
