“…We assume that for a symbol with M bits, the transmission power of OOK is P OOK , the power of PPM is given as P PPM =2/2 M • P OOK , DPIM has an average number of slots per symbol n = (2 M +3)/2, and thus the transmission power is given as [2] [3] : Figure.2 shows the average optical power of DPIM and PPM, normalized to OOK, versus the number of bits per symbol. For M=4, DPIM has an average power ~6.8dB lower than OOK, but ~2.2 dB higher than PPM.…”

Based on the atmospheric optical irradiance scintillation channel and an avalanche photodiode detector (APD) receiver communication system, this paper analyzes the error probability performance of digital pulse interval modulation (DPIM). Both the theory and the simulation results show that compared with PPM, the DPIM has a similar transmission efficiency, less bandwidth requirement, a marginally inferior error probability, and less complicated to implement.Hence, DPIM is more favorable in wireless optical communications system.

This paper presents a brief review of infrared communications systems, modulation techniques and in particular, a digital pulse modulation scheme known as digital pulse interval modulation (DPIM) for infrared (IR) communication systems employing intensity modulation with direct detection (IM/DD). DPIM code characteristics, power spectral density and error probability in terms of the packet error rate are discussed. Performance comparison is made with that of on–off keying (OOK) and pulse position modulation (PPM). For comparison, relevant expressions for both OOK and PPM are also presented. Using a threshold‐detector‐based receiver, we show that DPIM outperforms both OOK and PPM in terms of power efficiency and PPM in terms of bandwidth efficiency, by taking advantage of its inherent variable symbol duration. However, using a maximum‐a posteriori (MAP) detector it provides marginally inferior error rate performance compared with PPM. Copyright © 2000 John Wiley & Sons, Ltd.

“…3, we proposed dual-amplitude pulse interval modulation ͑DAPIM͒ as the modulation scheme for optical wireless indoor systems. The performance of DAPIM in the presence of both multipath intersymbol interference ͑ISI͒ and ambient background noise was compared with other modulation schemes, namely, on-off keying 4 ͑OOK͒, pulse position modulation 5 ͑PPM͒, and pulse interval modulation 6 ͑PIM͒. Particularly at a high bit rate, DAPIM offers improved performance in bandwidth and error rate as does dual-header pulse interval modulation 7 ͑DH-PIM͒.…”

The performance of code-division multiple access ͑CDMA͒ as a multiple-access technique for optical wireless communications is evaluated. The information data is modulated through dual-amplitude pulse interval modulation ͑DAPIM͒. Optical orthogonal code is used as the signature sequence. The upper bound and lower bound on the exact probability of errors per slot and per packet are derived in the presence of ambient background noise. We investigate the performance characteristics for various system parameters, including the SNR of the source information bits, receiver threshold, DAPIM order, and number of users.
