Analysis Bit Rate vs SNR Project Details
| Abstract |
Free Space Optical (FSO) communication systems offer a high‑bandwidth, license‑free alternative to traditional radio‑frequency links, but atmospheric turbulence causes fading that seriously hurts performance. This project provides research direction and implementation support for evaluating the bit error rate (BER) and signal‑to‑noise ratio (SNR) of several channel‑coding techniques under different atmospheric conditions. Using MATLAB‑based simulations, the study models turbulence with a log‑normal distribution for weak turbulence and a gamma‑gamma distribution for moderate‑to‑strong turbulence. The performance of single coding schemes— – convolutional coding, – low‑density parity‑check (LDPC) coding, and – trellis‑coded modulation (TCM) — is systematically compared with a concatenated coding architecture. The evaluation seeks the coding configuration that gives the highest
achievable bit rate while requiring the lowest SNR for various scintillation indices. The simulation framework serves as a practical guide for designing robust optical wireless links and shows that concatenated coding schemes provide better error‑correction capability and reduce multipath fading effects in turbulent FSO channels.
