Optical wireless communications utilizing a dicode PPM PIN-BJT receiver

Original results are presented for an optical wireless system employing dicode pulse position modulation (DiPPM) and a PINBJT receiver. When operating at 0.85 m and a bit rate of 10 Mb/s, a sensitivity of 51 dBm (Pe 10 ) is achieved, which represents a 10.3-dB improvement, as compared to an equivalent PCM system. The work also demonstrates that DiPPM achieves comparable sensitivities to those o...

Optical Wireless Communications Utilising Dicode Ppm Pin-bjt Receiver

Original results are presented for an optical wireless system employing dicode pulse position modulation (DiPPM) and a PIN-BJT receiver. When operating at 0.85 m λ μ = and a bit rate of 10 Mb/s a sensitivity of –51 dBm (Pe=10) is achieved and this represents a 10.3 dB over an equivalent PCM system. The work demonstrates that DiPPM achieves comparable sensitivities as that for the digital PPM fo...

Spectral characterisation of electronic cameras

In order to properly calibrate an electronic camera for a variety of illuminants it is necessary to estimate the spectral sensitivity of the camera. This spectral characterisation is obtained by measuring a set of samples of known spectral reeectances and by inverting the resulting system of linear equations. In the presence of noise, this system inversion is not straightforward. We describe se...

A spectral characterisation of t-designs

There are two standard approaches to the construction of t-designs. The first one is based on permutation group actions on certain base blocks. The second one is based on coding theory. These approaches are not effective as no infinite family of t-designs with t ≥ 5 is constructed with them. The objective of this paper is to give a spectral characterisation of all t-designs by introducing a cha...
