• These decoders operate on hard decisions (0’s and 1’s, or equiva lents) – Convolutional decoders can use soft -decision decoding. Anna University MCQ PDF Materials with Answers for Regulations 2017 all departments are uploaded for January 2021 Online Examination Preparation. Convolution codes offer an approach to error control coding substantially different from that of block codes. Convolutional codes are used extensively in numerous applications in order to achieve reliable data transfer, including digital video, radio, mobile communication, and satellite communication [9]. convolutional codes by termination, truncation, or tailbiting.

1. Convolutional codes were introduced in 1955 by Peter Elias. It uses short memory and connvolution operators to sequentially create coded bits. An example for a rate 1/2 convolutional code is shown below.
