In the direct quantization method, the IPD, OPD, ICC, and IID were quantized and transmitted.
The estimated channel information is quantized and transmitted to the destination together with the data symbols.
In the proposed methods, the IPD (or RPD), IID, and ICC were quantized and transmitted.
In the conventional PS, the IID, IPD, and ICC were quantized and transmitted, and the OPD were estimated at the decoder.
If one or several speech signals have been quantized and transmitted to the other device, the beamforming output is directly affected by quantization noise.
The covariance matrix was quantized and transmitted to the decoder following a previous KLT-based multichannel audio coding scheme [21], with 4 bits per non-redundant element.
To remove the aliasing terms caused by cascading different types of codecs, FAC additionally generates the aliasing cancellation signals, and then they are quantized and transmitted to the decoder.
It is noted that in some cases one measurement per sensor is used for localization and in the other cases when multiple measurements (i.e., z i (x,k) for several k's) can be made at each sensor, a sufficient statistic for localization from the multiple measurements can be computed before being quantized and transmitted.
For this reason, in real systems, the local statistics are quantized and then transmitted to the central processor; thus, a quantization noise is present.
The electric and magnetic fields described in Maxwell's equations are quantized, and photons appear as excitations of those quantized fields.
