Question.(5)

Pit 0 dBT -10 dB+ -20 dB+ -30 dB+ indoor 50 75 0 dB -10 dB -20 dB -30 dB 100 excess delay (na) P(x) 0 5 10 (b) outdoor (us) 2-For the power delay profiles in the Figure above, estimate the 90% correlation and the 50% correlation coherence bandwidths. 3- How large can the rms delay spread be, for a binary modulated signal BPSK with a bit rate of 25 kbps to operate without an equalizer? What about an 8-PSK system with a bit rate of 75 kbps? 4- If the channel is to be used with a modulation that requires an equalizer whenever the symbol duration T, is less than 100. Determine the maxim urban RF symbol rate that can be supported without requiring an equalizer. 5- If a mobile traveling at 30 km/hr receives a signal through the channel, determine the time over which the channel appears stationary (or at least highly correlated).
