Dual-Amplitude Pulse-Position Modulation

This chapter introduces dual-amplitude pulse-position modulation (DAPPM) and discusses its symbolic structure, power-spectrum density, bandwidth requirement, and channel capacity in an ideal channel. It is compared with on–off keying (OOK), pulse-position modulation (PPM), digital pulse-interval modulation (DPIM), and dual-amplitude pulse-interval modulation (DAPIM).
