Abstract
Embodiment herein provide a Bose-Chadhuri-Hocquenghem (BCH) encoder for generating a BCH signal. The BCH encoder (1) includes a memory for storing a minimum distance to be used for generating the BCH signal for a BCH code (n, k) and a polynomial generator for generating a generator polynomial for the BCH code (n, k) and encoding the generator polynomial to obtain the BCH signal. The polynomial generator includes a set of k registers (4) connected in series to receive the information bits and output an encoded bit based on a clock signal, a first gate (5) to receive a code length, a number of information bits, and the minimum distance as input, a second gate (6), and a finite field adder circuit (7) for determining a finite field sum of the output of each register of the set of k registers (4).
