A transmitter sends data at a bitrate of 10kbps using a bandwidth

of 100 kHz. The channel noise is measured to be N0=10e-10W/Hz. A receiver located 1 meter from the transmitter receives a 0.1W signal. For the communication protol being used, the recceived power must be greater than -20 dBm for successful reception.
(a)What is the required received power in Watts?   (b)What is the required received energy per bit?
(c)Assuming path-loss follows a two-ray ground propagation model, how far can the receiver travel from the transmitter and still achieve successful reception?
(d)What is the maximum data rate at which the transmitter can send information and still guarantee rerliable communication at the distance determined in (c)?
(e)What is the maximum possible bandwidth efficiency?
