Abstract
This study evaluates the bit error rate (BER) performance of a turbo-coded orthogonal frequency division multiplexing (OFDM) communication connection using a terrestrial/wireless free-space optical (FSO) channel, taking atmospheric turbulence into account. The Lognormal probability density function (PDF) statistically represents the turbulence-induced intensity fading in the presence of weak turbulence. Furthermore, for enhancing BER performance, a novel low-complexity turbo code which is a channel coding scheme, and OFDM are recommended. The analysis is carried out using the bandwidth-efficient 16-QAM (quadrature amplitude modulation) modulation technology. According to the simulation results of the proposed model, the 16-QAM modulation scheme, turbo coding parameter, and connection length should be taken into account to ensure system dependability. The simulation demonstrates that over the course of a link length, a reliable communication link (10–9 BER) may be molded for 1 km in weak turbulence fading conditions. For easiness SISO (single input-single output) system has been studied for sustaining targeted BER (10–9) in the existence of weak turbulence fading.
