Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: In this study, the authors evaluate the performance of an earth-to-satellite free-space optical link in terms of bit error rate (BER) for three intensity modulation (IM) schemes [on–off keying (OOK), M-ary pulse position modulation (M-PPM) and M-ary differential PPM (M-DPPM)] and direct detection receiver. The performance is analysed in the presence of atmospheric turbulence, beam-wander induced pointing error and ather conditions. Turbulence with beam wander effect is modelled using gamma-gamma distribution and the ather effects are incorporated using the Beer-Lambert law. They obtain closed form BER expressions for the above IM schemes using combined channel state probability density functions. They show that for the same average por, M-PPM offers the best performance, follod by M-DPPM and OOK schemes. Link performance degrades for all IM schemes with increase in the value of ground level refractive index structure parameter and bit rate. Presence of ather conditions like moderate, light and thin fog increase signal attenuation and this increase may be very high in case of thick and dense fog or clouds and can lead to link failure.
