Structured codes where the block of parity bits is linearly combined with the message bits (e.g., Generator and Parity Check matrices). information theory and coding by giridhar pdf

If the physical book is unavailable, professors often recommend complementary open educational resources (OER) or lecture notes provided on university domains (such as MIT OpenCourseWare or NPTEL). Conclusion

This module transitions from the source to the medium of transmission. This section focuses on data compression

: Discusses discrete and continuous channels, mutual information, and the Shannon-Hartley theorem (channel capacity).

Information theory is a mathematical framework developed by Claude Shannon in 1948. It quantifies data to determine how much information a message contains and how fast that information can be transmitted. Coding theory applies these concepts practically, using algorithms to compress data and protect it from corruption during transmission. The subject is generally divided into two main categories: 1. Source Coding (Data Compression)

The average information per symbol of the source is Entropy ($H(X)$): $$H(X) = - \sum_i p(x_i) \log_2 p(x_i)$$ quantifies the average information content of a source

"Information Theory and Coding" is a textbook ideally suited for:

The speed at which information is generated by a source.
