Abstract :
This correspondence compares OOK and low-order PPM signaling formats in terms of bit error probabilities versus required signal counts per bit. The results show that QPPM requires 3 dB less signal than OOK, while BPPM requires the same or slightly more than OOK for the same performance. Optimum APD gain values are from 200 to 400. When using QPPM, 
, and optimum gain, 60 signal counts/bit are required at 500 Mbits/s for a 10-6bit error probability.
