91. For improving the SNR and the reducing transmit power of the SAR simultaneously, airborne SAR often use high PRF (Pulse Repetition Frequency).

92. Dalton Bearing Service is proud to authorized distributor for SNR Bearing.

93. An improved algorithm for symbol synchronization and symbol decision are proposed. Their performance at different level of SNR and frequency offset are discussed by simulations.

94. The relation of the convergence of this algorithm with the spreading rate, interferential power, and the SNR (signal noise rate) is analyzed theoretically and examined through simulation.

95. The Forward Passage Gain (FPG) is an important factor that affects the detection Signal-to-noise Ratio (SNR) and dead band nonlinearity of Fiber Optic Gyroscope (FOG).

96. It is emphasized that under some poor SNR conditions, the"threshold effect"of non-coherent demodulator degrades seriously, even causes the receiver to be out of work.

97. Improving the echo SNR through signal processing at receiving terminal is a good method to increase the measuring range of airborne laser rangefinder.

98. A new method for testing the video signaltonoise ratio (SNR) of television tracking system was brought forward, in which 3D noise theory and digital image processing technique was adopted.

99. The channel of LEO satellite is different from wireless channels on the ground. Low SNR and large Doppler shift are the two characteristic of LEO satellite channel.

100. In this paper, the basic principle of coded excitation is introduced. Through acoustic intensity analysis(sentencedict.com), the maximum improvement of SNR of ultrasonic image with coded excitation is deduced.

101. The experiment results acquired from synthetic analog data proves better performance of the presented filter in eliminating the Rician noise at low level SNR.

102. This paper proposes a new speech enhancement algorithm to improve the quality of speech in low SNR environment.

103. Meanwhile, the approximate equation of pairwise probability of error was shown with SNR floor anti basic differential expression.

104. This paper expatiates on the validity of this method and brings forward the preconditions of improving SNR and increasing the virtual digit of signal meterage by interpolation filter.

105. However, in respect of a vibration acceleration signal, the signal to noise ratio (SNR) is often so small that the periodic impulse component is submersed in its intense background noises.

106. Offering SNR estimation method based on the quantization noise power spectrum.

107. From the non-cooperative point of view, the paper proposes a SNR estimator which is still relevant in the condition of unknown frequency uncertainty, symbol timing and rolloff factor.

108. Tore duce effective the multipath disturbance and multi-user interference and improve the SNR, time-domain equalizer is employed at the output of each array element of smart antenna.

109. In addition, based on FFT and remainder algorithm, the modulation rate and initial frequency of sub-sampling UWB LFM signal are estimated unambiguously in negative SNR.
