Question

Decide the Rician factor K [dB] for the LOS power of 10 [m W] and diffuse components power of I [mW1. (2) 1. 10 l k 1699 17 2. Assume your car, with Rx antenna perfectly aligned with base station Tx antenna, is moving with speed ‘v' of 60 Km/hour. Assuming carrier frequency of 100 MHz, find the Doppler frequency in [Hz]. Use a-(va) Cos θ and unit of [m] for' λ, and .v, in Per Doppler frequency you found in Problem 2, calculate the Level Crossing Rate (LCR) denoted as N(R) assuming that the specific signal level is 6 dB below the RMS level. Use formula (use result of problem 2 as in the formula below) (5) 、-C 3. .212 3.5
answer the question and write the formula

Answer 1

  
K = Specular Power/Nonspecular Power = V^2_1/P_dif K = B^2/2 sigma^2 = kd^2/2 sigma^2 = Specular Power/Nonspecular Power k(dB) = 10 log_10 k = 10 log_10 Specular Power/Nonspecular Power Specular Power = LOS Power = 10 times 10^-3 W Nonspecular power = diffuse power = 10^-3 W k = 10 log_10 10 times 10^-3/10^-3 = 10 log_10 10 = 10(1) = 10 {log^a_a = 1} No need to do square of multiply by 2
