Quantization Noise in Adaptive Weighting Networks

IEEE Transactions on Aerospace and Electronic Systems, 1984
Adaptive weighting networks can be implemented using in-phase and quadrature, phase-phase, or phase-amplitude modulators. The statistical properties of the quantization error are derived for each modulator and the quantization noise power produced by the modulators are compared at the output of an adaptive antenna. Other relevant characteristics of the

Quantizing Noise and Data Transmission

Bell System Technical Journal, 1968
Methods for calculating the power in the quantizing noise on digital transmission facilities have been known for some time. A more difficult but unavoidable problem is the effect that this noise has on data signals intended for analog transmission. This paper demonstrates that to assume that the noise will behave as a white Gaussian noise process will ...

Quantization noise, fixed-point multiplicative roundoff noise, and dithering

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1990
The author considers the characteristics of the error resulting when a continuous amplitude signal x/sub n/ is quantized and then multiplied by a constant multiplier a under fixed-point roundoff arithmetic. It is shown that the overall error of such an operation can be decomposed into two terms: one being a scaled version of the error due to the ...

Quantization noise of signal correlators.

2011
In radio-astronomy, spectra of noisy signals are often computed using digital auto-correlation techniques. To simplify the design of the many high-speed multipliers and averagers, coarse quantization is employed, using only a few digital levels. This thesis is a theoretical study of the penalty paid for such coarse quantization in the form of increased

Phase noise in quantized sine waves

ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Analysis of sampled and quantized signals has assumed no fixed relationship in time between the signal and the sampling clock. This assumption is invalid for some signals of importance: digitally synthesized sine waves, and NTSC color television signals. This results in an apparent interaction between sampling and quantization.
