Para alta eficiência de transmissão, são esperados bons esquemas de modulação. Este artigo enfoca o aprimoramento do esquema de modulação do sistema óptico turbo codificado de espaço livre. Um sistema óptico turbo codificado de espaço livre usando um novo esquema de sinalização denominado sinalização híbrida PPM-OOK (HPOS) é proposto e investigado. A fórmula teórica da taxa de erro de bit do sistema HPOS não codificado é derivada. Os desempenhos efetivos da taxa de informação (ou seja, capacidade do canal) do sistema turbo codificado HPOS proposto são avaliados através de simulação computacional em canal óptico de espaço livre, com cintilação fraca, moderada e forte. O desempenho do sistema turbo codificado HPOS proposto é comparado com o do sistema turbo codificado convencional OOK (On-Off Keying) e do sistema turbo codificado BPPM (Binary Pulse Position Modulation). Como resultados, o sistema turbo codificado HPOS proposto apresenta a mesma capacidade de tolerância ao ruído de fundo e à turbulência atmosférica que o sistema turbo codificado BPPM convencional, e possui capacidade 1.5 vezes maior.

Abstract: For high transmission efficiency, good modulation schemes are expected. This paper focuses on the enhancement of the modulation scheme of free space optical turbo coded system. A free space optical turbo coded system using a new signaling scheme called hybrid PPM-OOK signaling (HPOS) is proposed and investigated. The theoretical formula of the bit error rate of the uncoded HPOS system is derived. The effective information rate performances (i.e. channel capacity) of the proposed HPOS turbo coded system are evaluated through computer simulation in free space optical channel, with weak, moderate, strong scintillation. The performance of the proposed HPOS turbo coded system is compared with those of the conventional OOK (On-Off Keying) turbo coded system and BPPM (Binary Pulse Position Modulation) turbo coded system. As results, the proposed HPOS turbo coded system shows the same tolerance capability to background noise and atmospheric turbulence as the conventional BPPM turbo coded system, and it has 1.5 times larger capacity.
