摘要
An optical transceiver is provided for optical communications with additive noise compensation. The system and method are disclosed for the additive noise cancellation, which is typically a vibration noise, caused by moving platform, where the transceiver is located. The transceiver comprises an additive noise sensor and a digital signal processing (DSP) unit which implements variable step size technique to adjust the filter weight in the least square estimate of the noise signal. In the preferred embodiment the digital signal processing is applied both at the transmission and the receiving side. The optical device is packed for ground-satellite and inter-satellite communications applications with resistance to high-energy X-rays, gamma rays and cosmic rays. The optical device sustains its operation characteristics under launch load.
