Then the 15-dimensional VQ codebook is used to vector quantize
the diagonal edge blocks.
At the encoder, the ST-Q is used to quantize
the CS measurements of video sequence.
Again, in order to quantize
this toy model, we impose equal time commutation relations given by (17-19), and by means of normal mode functions [[psi].
In FDD systems, the effect of quantized CSIT is analyzed in  and , in which the authors use Grassmannian codebooks to quantize
the channel direction information and feedback to transmitters with frequency domain symbol extension.
Scientists had long assumed that only one way existed to quantize
physical parameters, but they lacked experimental evidence to support that belief.
To perform the information level modulation, the structured codebooks are designed using uniform quantizes
