## Information Theory, Coding and Cryptography.

Ranjan Bose’s chapter about cyclic codes begins with a riveting quote by Pascal, Blaise “We arrive at the truth, not by reason only, but also by the heart.” Quotes like this make a comprehensive book about information theory even more captivating. Linear Block Codes, block codes –every message m (size k) corresponds to a codeword c (size …

## Information Theory: Channel Coding, Channel Capacity.

Everything you’ve come to expect. Mindless, terror-filled panic rushes through me as I open the slides for my exam and can barely understand anything. About a week ago, I was pretty good at most of the things related to the subject, the subject. Yes, Information theory and coding techniques. It was supposed to be my subject …

## BCH code. Bose–Chaudhuri–Hocquenghem codes.

1950’s, the age of contemporary mathematics. This was the age when the mathematics in information theory boomed. From Claude Shannon developing the notion of Information theory in 1949 to BCH code being independently invented by three scientists in 1959, the era did see some really significant inputs in that era. ref Fun tangent, quick sort …
