Some General Equations

P_t: Transmitted power in mW
D_r: Receiver aperture diameter in meters
d: Distance between transmitter and receiver in meters
P_r: Received power in mW
L_p: Path loss in dB
N_0: Noise power spectral density in mW/Hz

Calculate Received Power

Power_received = fso.calculate_received_power(P_t, D_r, d)

Calculate Path Loss

Path_loss = fso.calculate_path_loss(P_t, P_r)

Calculate SNR

SNR = fso.calculate_snr(P_r, N_0)

Calculation of Losses

wl = wavelength
d= distance between transmitter and receiver
alpha= atmospheric attenuation coefficient
dt= diameter of transmitter antenna
dr = diameter of receiver antenna
pt = power total
pn = power of ambient noise
sigma_p = standard deviation of pointing error
sigma_s= standard deviation due to scintillation
gamma = initial intensity of optical beam
cn = refractive structure parameter
theta= angle of divergence
theta_mis = mismatch angle divergence

Attenuation Loss

attenuation_loss = fso.atmospheric_attenuation_loss(gamma, alpha, d)

Geometric Loss

geo_loss = fso.geometric_loss(dr, dt, d, wl, pt)

Misalignment Loss

misalignment_loss = fso.pointing_misalignment_loss(d, sigma_p, pt)

Atmospheric Turbulence

turbulence_loss = fso.atmospheric_turbulence(pt, cn, d, wl)

Polarising Loss Power

polarising_loss_power = fso.polarising_loss_power(pt, theta_mis)

Ambient Noise

ambient_noise = fso.ambient_noise(pt, pn)

Beam Divergence Loss

divergence_loss = fso.beam_divergence_loss(theta, d, pt)

Scintillation Loss

scintillation_loss = fso.scintillation_loss(sigma_s, pt)
