Abstract :
This paper introduced the work principle of dual-amplitude pulse position modulation, analyzed the transmission efficiency, channel capacity, power spectral density, and compared with the other modulation schemes as OOK, PPM, DPIM, DAPIM analyzed the bandwidth, information rate of unit and transmission capacity. Simulation show that DAPPM has better bandwidth efficiency than DPIM and PPM, DAPPM is more suitable transmission in the communication environment and the channel of encoded.
