Compared with the conventional variable gain solutions of LNA,which have more noise degradations when in low gain mode,this solution gives about 25dB variable gain range in 3dB steps,which would cause ultra low noise figure degradation by 0 3～0 5dB.

Algorithm for Uplink based on the control over noise rise, it can be effective to measure interference in system; Algorithm for Dwlink come from the total power of BS, which has a intu.

When system loads are close to the spread factor, joint detection cann t reach the need of system performance because of a SNR degradation.

An analysis of quantization noise in FM transmitter at intermediate offset frequencies;

Quantization noises of three types of Σ-Δmodulators are analyzed based on a linearized model'By using signal flow graphics method,each transfer function,quantization noise and quantization signal-to-noise ratio(SNR) is derived respectively.

Quantization noise in AD conversion will influence bias stability of FOG.

Then the variance of quantification noise and SNR loss are compared between minimization quantification and uniform quantification for the same conditions.

Based on the study of the influence of the quantification noise and the gray level noise on target feature image,the error model of the target feature image centroid coordinates is built.

In this paper,the formula of ranging MSE root of multiple frequency CW radar is concluded when the quantification noise is considered.
