The high data rates enabled by free-space optical communication links and additional factors, such as the unregulated spectrum, make them an attractive solution in future geostationary feeder link applications with capacities beyond one Terabit per second. However, optical links through the atmosphere are heavily affected by atmospheric turbulence, leading to significant scintillation. Transmitter diversity is an effective way to improve the signal quality of optical links. Transmitter diversity with Phase-Division in Bit-Time is a novel scheme for mitgating interference and thus enabling the use of equal wavelengths for multiple transmitters. This paper will evalute the Phase-Division in Bit-Time transmitter diversity scheme and present measurement results from a lab testbed.

应用于光 GEO 馈线链路的分相发射机分集



自由空间光通信链路和其他因素(例如不受管制的频谱)实现的高数据速率使其成为未来地球静止馈线链路应用中有吸引力的解决方案,容量超过每秒 1 太比特。然而,穿过大气层的光链路受到大气湍流的严重影响,导致明显的闪烁。发射机分集是提高光链路信号质量的有效途径。位时相分发射机分集是一种新颖的方案,用于减轻干扰,从而使多个发射机能够使用相同的波长。本文将评估位时发射机分集方案中的相分并展示实验室测试台的测量结果。
