WebThe second sub-block is n/2 parity bits for the payload data, computed using a recursive systematic convolutional code (RSC code). The third sub-block is n/2 parity bits for a known permutation of the payload data, again computed using an RSC code. Thus, two redundant but different sub-blocks of parity bits are sent with the payload. WebConstraint length will be 3. Thus, for the convolutional code, it is said that the output stream shows dependency on previously-stored bits in memory along with the present input bits. Reed - Solomon Code. It is a linear block code. It takes a block of data and insert or add redundant bits before transferring the message.

WebUnder this definition codes such as turbo codes, terminated convolutional codes and other iteratively decodable codes (turbo-like codes) would also be considered block codes. A non-terminated convolutional encoder would be an example of a non-block (unframed) code, which has memory and is instead classified as a tree code. Websome block codes such as BCH and Reed-Solomon codes and convolutional codes which will be discussed in this paper. The paper is organized as follows. In Section II the concept of FEC will be introduced. Section III discusses first block codes in general and then some particular cyclic codes, namely BCH codes and Reed-Solomon codes ...
