P & le Question 3: (Marks: 8+2+5) Channel impulse response in a local propagation site is measured as, 10-4 h(T) = 8(T- 1 x 10-6) n3 + 1 n=0 kolog 12 Sió 2/ 1 Page 2 of 3
(a) Find the rms delay spread of this multipath propagation channel. (Ⓡ) (b) For what maximum symbol rate (in symbols per second), the channel can be considered as a flat fading channel? (2) (c) For the maximum data rate found in part-(b), devise a single-carrier system. What type of modulation should be used and what should be the typical range of transmission bandwidth so that Bit Rate is very high (5~10 times) compared to the symbol transmission rate; but transmission bandwidth does not cross coherence bandwidth. Quantify your answers properly. (5). .
