Question: If a baseband binary message with a bit rate Rb = 100kbps is modulated by an RF carrier using BPSK, answer the following: i.

If a baseband binary message with a bit rate Rb = 100kbps is modulated by an RF carrier using BPSK, answer the following: i. Find the range of values required for the rms delay spread of the channel such that the received signal is a flat fading signal. ii. If the modulation carrier frequency is 5.8GHz, what is the coherence time of the channel, assuming a vehicle speed of 30km/hr? Calculate the received carrier frequency if the receiver is moving towards the transmitter. iv. Is the channel fast or slow fading?
