Rx band noise calculation
WebFor thermal noise, its spectral density is given by N 0 = kT, where k is the Boltzmann constant in joules per kelvin, and T is the receiver system noise temperature in kelvins. The noise amplitude spectral density is the square root of the noise power spectral density, and is given in units such as /. See also. Noise-equivalent bandwidth WebEx. 1: Let’s calculate the thermal noise floor of the 200 kHz channel bandwidth used by GSM. We just calculate the thermal noise in 200 kHz bandwidth: kTB for GSM (200 kHz) = -174 dBm/Hz + 10 log (200.000 Hz) = -121dBm The -121dBm is therefore the absolute lowest noise power we get in a 200 kHz GSM channel.
