We’ll be talking about rate 1/p codes. Overview of Convolutional Codes (2) ¾A convolutional code is specified by three parameters or where – k inputs and n outputs • In practice, usually k=1 is chosen. – is the coding rate, determining the number of data bits per coded bit. – K is the constraint length of the convolutinal code (where the encoder has K-1 memory elements).

of bits in the encoder memory that affects the generation of n output bitsPratishtha Shira Ram introduCtion to Convolutional Code (Cont’d) The convolutional codes map information to code bits, but sequentially convolve the sequence of information bit according to some rule. The convolutional coding can be applied to a continuous data stream as well as to blocks of data whereas the block codes can be applied only for the block of data. Convolutional codes Tomashevich Victor. Introduction • Convolutional codes map information to code bits sequentially by convolving a sequence of information bits with “generator” sequences • A convolutional encoder encodes K information bits to N>K code bits at one time step • Convolutional codes can be regarded as block codes for which the encoder has a certain structure such that Convolutional Coding - Convolutional Coding In telecommunication, a convolutional code is a type of error-correcting code in which m-bit information symbol to be encoded is transformed into | PowerPoint PPT presentation | free to view An 'error event' is any path segment in a trellis that deviates from the correct path | PowerPoint PPT presentation | free to view. Convolutional Codes 1 - Walk through the trellis and compute the Hamming distance between that branch of At the end of the trellis, select the path with the minimum cumulative Convolutional Codes 14 •In practical application, convolutional codes have code sequences of finite length. When looking at the finite generator matrix of the created code in time domain, we find that it has a special structure.
