This slide presents issues related to coarse quantization.
Please notice that an independent Additive White Gaussian Noise channel with mean zero and standard deviation 1 is assumed for each receive antenna.
The figure exemplifies a 2-bit quantization process which generates four quantization bins of equal probability (25%).
It can be easily calculated that the quantization thresholds are 0 and plus minus 0.6745, and the corresponding four bin-average values are plus minus 0.3247 and plus minus 1.2711. |
