Cyclic Codes

: A subset of block codes (like BCH and Golay codes) that are easier to implement using shift registers.

Prof. Giridhar’s approach often begins not with the math, but with the intuition: "Information is the resolution of uncertainty." information theory and coding by giridhar pdf

• Polynomial Representation: Instead of matrices, data is treated as polynomials (e.g., $x^3 + x + 1$).
• Generator Polynomial ($g(x)$): All valid codewords are multiples of $g(x)$.
• Cyclic Redundancy Check (CRC): The most common application used in Ethernet
