Question

Please explain with details. How can be decide the prefix and suffix code for Lempel Ziv Algorithm.

There cannot be given more information. The question is like that.

This is only one question. All steps are interconnected

(d) Determine the compression rate of the algorithm, based on the solution found in the previous sub-task. (e) Name two conditions that help to improve the compression rate of the algorithm.

Question 5: Source Coding Consider a source that produces a random sequence without memory. The elements of the sequence are drawn from Q E {A, B}, with P(A) = 1/3 and P(B) = 2/3. (a) Evaluate if the following sequences are typical: true false АВВBAAAВB ВВBBBBAAA ВВВBBBBBB ВАВАВBАBB (b) If e → o and the length of the sequence is n, how many e-typical sequences exist? Explain the answer. Now the sequence symbols of the source are mapped to bits. An example sequence is given as q = [0110100110001011] (c) Encode the sequence q with the Lempel-Ziv's algorithm (LZ78).
