From this, the carrier to noise density ratio can also be calculated for use in further analysis. This ratio comes from Eq. A.2.2.3.7. (A.2.2.3.7) where is the carrier to noise signal ratio, in decibel-Hertz, is the energy per bit to noise power ratio in decibels, and R is the data rate in bits per second.
What is a decibel (dB)?
Convert from a power ratio to dB: a. 50 . b. 0.005 . c. 800 . d. 1/2,000,000 . e. 64 . Convert from dB to a power ratio: a. -60 dB . b. 57 dB . c. 53 dB . ... To get a connection at the maximum rate of 54 Mbps, we will need a signal to noise ratio at least 20 dB better than the minimum assumed above. What will be the realistic distance to ...

For HDR transmission, for each input bit, the ratio between the power of On symbol and the power of Off symbol of the transmit signal in the WUR data field shall be larger than . 20 dB. For LDR transmission, for each input bit, the ratio between the averaged power over On symbols and the averaged power over Off symbols of the transmit signal in ...

Determine the minimum bandwidth required to achieve a P(e) of 10-7 for an 8-PSK system operating at 10 Mbps with a carrier-to-noise power ratio of 11.7 dB. Solution From Figure 2-40, the minimum Eb / No ratio to achieve a P(e) of 10-7 for an 8-PSK system is 14.7 dB.
