Investigation of Binary Error Probability for an Integrate-and-Dump Receiver as Output Quantization Increases.
Abstract
This thesis effort focuses on direct detection optical communications systems which use receivers classified as photon counters, or integrate-and-dump receivers. These systems determine the received message estimate based upon the number of photons or counts accumulated in the specified reception time period, T. The binary error probability for integrate-and-dump receivers is developed. The combination of the optical modulator, optical channel, and optical detector is characterized as a discrete memoryless channel (DMC). Maximum a posteriori (MAP) decision criteria are developed to enable optimal post-detection processing. The effect of quantizing the output is addressed for both ideal unity gain detector and avalanche detector optical systems. Multilevel Amplitude Keying is used to calculate specific probability of error values, and the channel cutoff rate is used to investigate probability of error bounds.
