The communication channel bandwidth uses is 25 MHz centered at 1GHz and uses BPSK. The noise power spectral density of the channel is 10^-9 W/Hz. The channel loss between the transmitter and receiver is 25dB. The application requires a BER of less than 10^-4. Determine the minimum transmit power required.arrow_forward

The noise power (in watts) measured in a 40MHz Wifi channel is 230*10^-6 Watts. The access point (AP) output power is 600 mW and only uses 256QAM and has a data rate of 400Mbps. The channel losses can be modeled as 0.4dB/meter. An application on your phone requires a BER of < than 1*10^-4.
