Abstract:

Probability of bit error Pb performance for a turbulent, atmospheric, optical, communications link with convolutional error detection and correction coding was investigated. The codes investigated were all rate 12 codes with constraint lengths ranging from 3 to 7. It was assumed that the coded data stream was sufficiently interleaved so that the turbulent channel could be considered memoryless. A theoretical bound on P sub b, given by Viterbi for a memoryless channel, was used to plot curves of P sub b versus the signal intensity of last transmitter. These curves were plotted for three different levels of atmospheric turbulence and three different levels of background light.
