In this paper, the synergy of the channel coding and aperture averaging is applied to the downlink optical channel for the low earth orbit (LEO) satellite. Bit error rates (BER) of the convolutional code and low-density parity code (LDPC) are evaluated versus different diameters for the optical systems with avalanche photodiode (APD) receivers.

Atmospheric turbulence produces fluctuations in the irradiance of the transmitted optical beam, which is known as at-mospheric scintillation, severely degrading the link performance. Turbo product codes (TPC) has attracted much attention for its high coding rate and strong abilities of defeating long burst errors, which is a good choice for the highly(More)
