# These MCQs are very helpful for preparation of academic & competitive exams. If the endpoints of the line are P5 P6 and the corresponding code is 0001 and

Each convolution imposes a constraint between bits. Several convolutions introduce the redundancy. J.-M. Brossier. Coding and decoding with convolutional

2. n output bits are generated whenever k input bits are received. 3. The current n outputs are linear combinations of the present k input bits and the previous m×k input bits. In telecommunication, a convolutional code is a type of error-correcting code that generates parity symbols via the sliding application of a boolean polynomial function to a data stream. The sliding application represents the 'convolution' of the encoder over the data, which gives rise to the term 'convolutional coding'.

In simulating of a given convolutional codes, there are two steps: (1) Setting up a file with the trellis structure and (2) Viterbi decoding using this structure. 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. This code maps b k to (c k1, c k2), where the state is (b k, b k-1, b k-2), and coded bits (c k1, c k2) are convolution (i.e., mod 2 sum) of Welcome to Our Data Compression Page Unit - II.

The Fano metric indeed mirrors the above intuitive observation by using a linear bias with respect to the code rate. Graduate Institute of … 2017-10-29 Deep Learning is a subfield of machine learning concerned with algorithms inspired by the structure and function of the brain called artificial neural networks.Deep learning is a machine learning technique that teaches computers to do what comes naturally to humans: learn by example. Deep learning is a key technology behind driverless cars, enabling them to recognize a stop sign, or to proposed RC LDPC convolutional code family theoretically covers all the rational ratesfrom 0 to 1. We proveanalyticallythat all the members of the RC family are si-multaneously capacity achieving. The RC LDPC convolutional code family enables a system to conveniently adapt to varying channel conditions.

Code rate = 0 . Solution: Part A is “Not linear” because the 000 codeword is missing—because the sum of any two codewords must be a codeword for a linear code, the absence of 000 makes the code
