1. Consider a two-ray channel with impulse response h(t) = α₁8(t) + α₂8(t – 0.022µs). Find the distance separating the transmitter and receiver, as well as α₁ and α₂, assuming free-space path loss on each path with a reflection coefficient of -1. Assume the transmitter and receiver are located 8m above the ground and that the carrier frequency is 900 MHz. 2. Let the two inputs of a modulator x(t) is given as a passband signal u(t) = sinc(100t) and a carrier signal c(t) = cos(400лt) whose frequency content is centered at fo = 200 Hz. Use MATLAB to complete the tasks below. Attach your codes and plots (no screenshot). All plots must be clearly labelled with readable font size. Plot u(t) and [U(fƒ)]. a. b. Plot c(t) and [C(f)]. c. Plot x (t) and [X(ƒ)]. d. Plot the in-phase and quadrature components of x(t). 25 5+5 1. Consider a two-ray channel with impulse response h(t) = α₁8(t) + α₂8(t – 0.022µs).
