Create a gist now. Instantly share code, notes, and snippets.This program implements a midrise lloyd-max quantizer, for optimal. quantization of a random variable demonstrating a Gaussian PDF. The indices produced by an -level quantizer can be coded using a fixed-length code using bits/symbol.(minimum mean-square quantization error) solution, and the resulting pdf-optimized (non-uniform) quantizer is referred to as a LloydMax quantizer, named after two people who This course covers lessons on information theory and coding, entrophy, block code and its properties, huffman coding,Shannon-Fano-Elias, arithmetic coding, information channels, Lloyd-Max Quantizer and vector quantization. Opt-2. Lloyd-Max quantizer design. Based on the optimality conditions given above, an iterative algorithm whichUsully, there are are predictive coding and entropy coding blocks attached inside the coding scheme, and the overall compression success is determined by their hybrid use. 4. Design a Lloyd-Max quantizer. 5. Distinguish between uniform and non-uniform quantization. 6. Define rate-distortion function. 7. State source coding theorem. 8. Determine the minimum possible rate for a given SNR to encode a. quantized Gaussian signal.

Iterative Lloyd-Max Quantizer. Let us define some terms: ti Quantization value i. The quantization values should be ordered, such that t1 < t2 < L < tn .minimum and maximum input values, they could be placed uniformly throughout the range, at locations The Lloyd-Max quantizer is designed nals using damped sinusoids, IEEE Trans. on Signal Processing, to be the same for all the coecients in an M -term, and vol. 53, pp. 38313846, 2005. its design requires both the number of terms to be coded [4] R.
