Receiver Performance
Receiver performance is an important factor in the FSO system design. The FSO design depends on the performance of the receiver's capability to detect 1s and 0s from the incoming optical signal. Bit error rate (BER) is a figure of merit to measure receiver performance. Receiver sensitivity is another performance-measuring standard for optical detectors and is important for FSO design. Finally, the signal to noise ratio (SNR) can be regarded as the absolute quantitative measure of the signal.
Bit Error Rate
During the transmission of data through an optical channel, it is desired that the receiver be able to receive individual bits without any errors. Errors occur when a receiver fails to detect an incoming bit correctly. ...
