Abstract
Original practical and theoretical results (λ= l·523 μm) are presented for both optimal and suboptimal detection of digital PPM. When operating with 16 slots of 20 ns duration, the sensitivity was measured to be 46·6 dBm for optimal detection, and 45·9 dBm for suboptimal detection. It is concluded that suboptimal filtering significantly reduces receiver complexity, and results in a degradation in sensitivity of only 0·7 dB.
