ii Consider a simple 5G wireless network which consists of one base station, one near user and one far user. Assume that both users are operating with NOMA scheme with the channel bandwidth, W = 5 MHz. Base station allocates 60 % of the total transmit power ( 16 dB ) to the far user and 40 % of the power to the near user. The channel gain between the user and the base station is modelled by comprising Log-normal shadowing, $ = 5 dB, Rayleigh fading distribution, Ihal = 3dB for near user , Inf = 0dB for far user and the distance between the near user and the base station d = 50m and the distance between the far user and base station d = 500m, path loss exponent, v = 2. Noise power spectral density, N,W =-30 dBm . Estimate the sum rate of the wireless network using NOMA scheme? (Total 20 Marks)
