Current Topics in Behavioral Neurosciencesately 20 dB (homodyne detection can reach 23 dB), allowing for longer distance transmission under the same power. Furthermore, coherent optical communication systems are more conductive to the suppression of atmospheric turbulence and channel fading. This chapter introduces the concepts behind coher

Sensitive Social Work Research, the background light and thermal and scattered particle noise have a significant impact on the performance of the communication system, and the IM/DD can not reach the theoretical limit of detection sensitivity. Under the identical link distance, bit error rate (BER), and code rate conditions, the

Spatial angular collimation cannot be guaranteed at the receiver end when the aberrated signal light is mixed with the local oscillation light, which reduces the mixing efficiency and signal-to-noise ratio of the system.

Optical Wirelss Coherent Detection: An Overview,Free-space optical communication (FSOC), also known as wireless optical communication (WOC), is a communication technology that uses laser beams as information carriers to directly transmit data, audio, and video signals in space (Lawrence and Strohbehn in Proc IEEE 58:1523–1545, 1970).
