Z. Ghassemlooy et al., A NEW MODULATION TECHNIQUE BASED ON DIGITAL PULSE INTERVAL MODULATION(DPIM) FOR OPTICAL-FIBER COMMUNICATION, Microwave and optical technology letters, 10(1), 1995, pp. 1-4
A novel digital pulse time modulation (PTM) technique called digital p
ulse interval modulation (DPIM) is presented in which the input signal
information is transmitted by the time intervals between two succeedi
ng pulses. DPIM has simplicity of circuit configuration combined with
other attractive features of digital pulse position modulation (DPPM)
for optical-fiber communications. This article derives theoretical exp
ressions for transmission capacity, code characteristics, and power sp
ectral density (PSD) and the analytical results are compared with expe
rimental data. (C) 1995 John Wiley & Sons, Inc.
