Unformatted text preview: of path loss with [dB] = 4 as well as Rayleigh fading. The transmit power at the base station is P t = 100mW, the system bandwidth is B = 30 KHz, and the noise PSD is N0 =10 14 W/Hz. Assuming BPSK modulation, we want to Fnd the cell coverage area (percentage of locations in the cell) where users have average P b less than 10 4 . a. Find the received power due to path loss at the cell boundary. b. Find the minimum average received power (due to path loss and shadowing) such that with Rayleigh fading about this average, a BPSK modulated signal with this average received power at a given cell location has P b < 10 4 . c. Given the propagation model for this system (simpliFed path loss, shadowing, and Rayleigh fading), Fnd the percentage of locations in the cell where under BPSK modulation, P b < 10 4 . E.Mahmoodi...
