A signal to noise power ratio estimation system for multi-carrier communication includes a phase rotator, a power estimator, a channel gain calculator, an average and selection device, a combination and calculation device and a decibel (dB) transformation device. The signal to noise power ratio ...
dB means a ratio measurement relative to *something* (ratio = 10^(dB/10)). +10 dB means 10 times bigger and -10 dB means 10 times smaller, so -40 dB means 10x10x10x10 = 10000 times smaller. dBm means dB relative to 1 mW, so 20dBm is 100mW, and -20dBm is 10uW. Wifi trans...
