What is Free Space Path Loss? Imaginary space where no matter exists is called free space. Free Space Path Loss (FSPL) is loss when electromagnetic wave pass through free space. When calculating link budget, there are losses because of atmosphere, rain, polarization, etc. FSPL is the biggest loss in various loss. Dervation of Free Space […]
Eb/N0 is the ratio of energy per bit to noise density. Eb/N0 is described below: \[\frac{E_b}{N_0} = \frac{C}{N_0}\frac{1}{B}\] where \(C/N_0\) is the carrier-to-noise ratio, \(B\) is the bit rate. Thus, Eb/N0 can be considered as the carrier-to-noise ratio divided by the bit rate.
Binary Phase-Shift Keying (BPSK) is one of the modulation methods of Phase-Shift Keying (PSK), which uses two phases. BPSK signal is descrived as below. \[s(t) = A\cos{(2\pi ft+\phi)}\] where \(A\) is amplitude of carrier wave, \(f\) is frequency of carrier wave. \(\phi\) is phase depending on signal, Using this equation, BPSK signal can be shown
EIRP is the power required when the antenna is replaced by an isotropic antenna, and can be calculated from the transmit power, feed line loss, and gain of the transmit antenna. This article explains the meaning of EIRP and how to calculate it. Table of Contents What is EIRP? EIRP stands for Equivalent Isotropically Radiated
