“…Also Gaussian distributed noise is not perfectly suitable for photon counting receiver plus PMT/APD amplifier. Therefore, packet error rate [8], [9] with a combined detection model of Poisson distributed photon counting plus Gaussian multiplication and thermal noise [11] is worth to be analyzed. In [12], the authors analyzed the bit error performance of OOK and PPM in UV scattering communication system based on this model.…”

Ultraviolet scattering communication has the capability of none-line-of-sight transmission, but it is limited by low receiving power and data communication rate. In this paper, digital pulse interval modulation (DPIM) and dual head pulse interval modulation (DHPIM), which have variable intensity modulation order and no requirement for symbol synchronization, along with on-off keying (OOK) modulation and pulseposition modulation (PPM) are analyzed with packet error rates for ultraviolet scattering communications. To match with the photon counting detection system, a detection model of Poisson counting plus Gaussian photon multiplication and thermal noise is adopted. Using this model, an accurate threshold equation is derived. This adaptive threshold minimizes the packet error rate according to power, rates and other parameters in system structure. Simulated packet error rates of OOK, PPM, DPIM and DHPIM are compared in different scattering channels in this paper.

“…Here the following assumptions are made to attain the probability of errors for DH-PIM [6,18,19]: (1) line-of-sight channel with no multipath dispersion; (2) no path loss; (3) no artificial light interference; (4) no bandwidth limitations imposed by the transmitter and receiver; (5) H 1 and H 2 are equally likely; and (6) the dominant noise source is the background shot noise, which is assumed as a white Gaussian. Using a threshold detector with a threshold level set mid-way between logical zero and one, the probability of slot error for DH-PIM can be expressed by [9] …”

“…Therefore, in the cases of erasure and false alarm errors, symbols following the erroneous slot will be shifted making it pointless to calculate the bit error rate (BER). Therefore, it is essential to base the analysis on the packet error rate (PER) [9,18].…”

SUMMARYThis paper assesses the performance of dual header pulse interval modulation (DH-PIM) over indoor optical wireless systems. DH-PIM being anisochronous scheme offers a built-in symbol synchronization capability. Theoretical and simulation results demonstrate that DH-PIM offers shorter symbol length, improved transmission rate and bandwidth requirement and a comparable power spectral density profile compared with digital pulse interval modulation (DPIM) and pulse position modulation (PPM) schemes.It is shown that DH-PIM 2 ; with wider pulse duration is the preferred option when the available channel bandwidth is limited and higher optical power is tolerable. Whereas DH-PIM 1 ; with narrower pulse width, exhibits comparable power requirements but a marginally higher bandwidth compared with DPIM, and is also more bandwidth efficient than PPM at the cost of increased power requirement. However, at higher bit resolutions, i.e. M57; DH-PIM 1 is both bandwidth and power efficient compared with PPM. Error rate analysis show that DH-PIM offers improved packet error rate compared with on-off-keying (OOK) and DPIM, but marginally inferior as compared with PPM. The power requirement and penalty due to intersymbol interference for non-dispersive and dispersive channels is analysed and the results show that for given parameters, DH-PIM requires marginally higher optical power compared with PPM and DPIM, but it supports the same bit rate at much less bandwidth requirement.
