This study considers a data collection system using optical space communication technology. The transmitters of the system asynchronously send their data to a base station using optical CDMA strategy. Because of different propagation characteristics, the intensity of the optical signals may not be the same at the base station. In this paper, we introduce a hard limiter to reduce the influence of this variation of signal intensity to the communication performance. The numerical results derived by computer simulation show the performance improvement by the introduction of a hard limiter, but for the improvement, it is required the threshold of the HL is optimized.
