Up to ten of the most intense ion peaks (minimum signal noise ratio: 50) were selected as precursors for MS/MS acquisition, excluding common trypsin autolysis peaks and matrix ion signals.
The MDA, in units of microcurie per microliter, was determined by requiring a minimum signal to noise ratio of 5 for the measured voltage.
For analog network coded transmission, we propose suboptimum schemes based on matched filtering and semidefinite relaxation of maximising the minimum signal to noise ratio.
Two suboptimum ANCTB algorithms are designed, namely, Matched Filter (MF) and semidefinite relaxation (SDR), which is based on the semidefinite relaxation of maximising the minimum signal to noise ratio problem.
In the one user scenario, the hierarchical modulation combined with a convolutional code is designed to achieve the objective bit error rates of two data channels with different priority level by an overall minimum signal to noise ratio.
Physical interference model is defined by formula (1), where β is the minimum signal to noise ratio (SNR) for successful receptions, N is the ambient noise power level, and a denotes the signal power decays with respect to d(v i,v j ), p k and p i denote the power level chosen by node v k and v i, respectively.
The nuisance field describes the acceptable interference level of the WSD at the location of a broadcast reception antenna, comprising of noise (N) plus a minimum signal to noise ratio (SNR) and the unwanted signal contributions ( N U DVB-T ) from other DVB-T transmitters: U dBm = ( N + SNR ) ⊕ N U DVB-T 1 ⊕ N U DVB-T 2 ⊕ … ⊕ N U DVB-T n (2).
The nonlinear joint tx-rx processing is formulated as an optimization problem to maximize the minimum signal-to-interference noise ratio (SINR) of streams to guarantee the fairness among streams of each user.
Monoisotopic peak masses were automatically determined within the mass range 800 4000 Da with a signal to noise ratio minimum set to 30.
Monoisotopic peak masses were automatically determined with a signal to noise ratio minimum set to 5 and a local noise window width of m/z 250.
