[Solved]-Q4 Consider Power Delay Profile Typical Urban Mobile Radio Channel Given Figure Q4 Scenari Q37233188

Q4. (a) Consider the power delay profile of a typical urban mobile radio channel, as given in Figure Q4. For this scenario [8 Marks] (i) Determine the 50% coherence bandwidth of the channel. (ii) Will this channel be suitable for AMPS (which has a baseband signal bandwidth Bs – 30 kHz) and GSM (which has a baseband signal bandwidth Bs-200 kHz) service without the use of an equaliser? [2 Marks] (ii) In a GSM system with the carrier frequency f 2.0 GHz, a mobile moves at a speed of v-90 km/h. Estimate the Doppler spread of the corresponding channel. [2 Marks] [1 Marks] (iv) Is this channel classified as slow or fast fading? P,(T) 0 dB -10 dB -20 dB -30 dB 5 T (usec) Figure Q4 Show transcribed image text Q4.
