Practice these MCQ questions and answers for preparation of various competitive and entrance exams. A directory of Objective Type Questions covering all the Computer Science subjects. 2.Interleaving process permits a burst of B bits, with l as consecutive code bits and t errors when a) B <= 2tl b) B >= tl c) B <= tl/2 d) B <= tl ANSWER: d) B <= tl. 3.The code in convolution coding is generated using a) EX-OR logic b) AND logic c) OR logic d) None of the above ANSWER: a) EX-OR logic.

For generating a convolutional code, the information is passed sequentially through a linear finite-state shift register. The shift register comprises of (-bit) stages and Boolean function generators. A convolutional code can be represented as (n,k, K) where. k is the number of bits shifted into the encoder at 1.Encoding data using convolutional codes – Encoder state – Changing code rate: Puncturing 2.Decoding convolutional codes: Viterbi Algorithm Save Save MCQ DC PPT 15.pptx 16 2 7 12 17 3 8 13 18 4 9 14 19 5 10 15 20 Representation of structure of convolutional code. a. a code tree b. a state Multiple choice questions on Digital Communication topic Channel Coding.

S. Han Sequential Decoding of Binary Convolutional Codes 12 part of the optimal code path is weaker at higher code rates. 6. 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.
