2016-07-05 Convolutional codes have memory that uses previous bits to encode or decode following bits It is denoted by (n,k,L), where L is code memory depth Code rate r is determined by input rate and output rate: input 1 output r r r = < Convolutional Coding & Viterbi Algorithm Er Liu (liuer@cc.hut.fi) The main feature of a Convolutional Network is the convolution operation where each filters goes over the entire input image and creates another image. Also you can watch the video where I explain how they work in a simple way. The Convolutional Neural Network tutorials also will explain the code to create it and represent it in a 3D visualization.

In this chapter we will concentrate on rate-1/n binary linear time-invariant convolutional codes, which are the simplest to understand Se hela listan på tutorialspoint.com Convolutional Codes • Convert any length message to a single ‘codeword’ • Encoder has memory and has n outputs that at any time depend on k inputs and m previous input blocks • Typically described by 3 parameters: – n= no. of bits produced at encoder output at each time unit – k= no. of bits input to encoder at each time unit Convolutional Codes 5 •Convolutional codes were first introduced by Elias in 1955. •The information and codewords of convolutional codes are of infinite length, and therefore they are mostly referred to as information and code sequence.
