Advantages of vector quantization over scalar uantization?

Answer 1

Advantage of VQ over SQ:

1.For a given rate, VQ results in a lower

distortion than SQ.

2.If the source output is correlate,

vectors of source output values will

tend to fall in clusters.

3.Even if no dependency: greater flexibility.

Answer 2

Vector quantization can achieve higher compression ratios compared to scalar quantization by capturing correlations between adjacent data points. It can also offer improved reconstruction quality since it retains more information about the original signal. Additionally, vector quantization is better suited for encoding high-dimensional data or signals with high complexity.

Answer 3

Vector is better but complex. So it has disadvantages too !!
