Probability Of Error Vs Snr

probability of error better than signal to noise ratio, How ? I know that probability of error is monotonically inversely proportional to singal-to-noise ratio. But if weights are assigned to probability of error as how it bit error rate calculation is done to signal-to-noise ratio, will it give any better results? 374.pdf Topics bit error rate test Probability × 404 Questions 1,938 Followers Follow Signal to Noise Ratio × 117 Questions 22 Followers Follow Jul 23, 2015 bit error rate vs snr Share Facebook Twitter LinkedIn Google+ 0 / 0 Popular Answers Olcay AKAY · Dokuz Eylul University Signal-to-noise ratio (SNR) is a well-known measure of how the signal and noise power compare against each other. Obviously, bit error rate example it directly affects the probability of error performance of a system. Noise is outside of the control of the user. But, in certain applications, the signal power can be increased to gain advantage against noise. For example, if you are designing the transmitter of a communication system, you can reduce the effect of noise by increasing the power of the transmitted signal. This incerases the SNR and reduces

Jul 24, 2015 Abdelhalim Zekry · Ain Shams University Dear Sanndhi, Adding to what has been said by Akay, the communication systems are characterized by a minimum signal to noise ratio for acceptable received signal by the destination. This is called a quality of service. In digital communication systems, the quality of the detected signal at the receiver is measured by the b

You need know the type of modulation to be used, Bandwidth, the noise of the system etc... Look up "Link Budget", Sensitivity (Equation), Eb/No Curves, and BER Curves. SNR bit error rate is one variable of several that determine what the likelihood of receiving Correct data is. i.e. 1Bit out of 1x10^7 Bits will be incorrect.
