A next generation optical wireless communications standard is currently established, denoted as IEEE 802.15.7r1, targeting data rates between 1 Mbit/s and 10 Gbit/s. Selecting an appropriate transmission scheme is one of the critical tasks. Following

We report a visible-light wireless point-to-point communication link operating at 513 Mbit/s gross transmission rate (net 450 Mbit/s). The bit-error ratio of the uncoded data was smaller than 2 · 10-3 for an illumination level of 1000 lx. The link w

For future short- and mid-range industrial applications, optical wireless (OW) communication systems are expected to play a major role. When moderate transmission rates (100 Mb/s range) are required, OW communications present a viable and promising t

We revisit the packet multiplexer with a discrete-time single server queue of limited capacity, and we derive a set of exact closed-form solutions for the major performance measures, such as the distributions of queue length, waiting time and number

In this letter, we present an exact closed-form solution for the probability distribution of the packet batch-size at the output ports of unbuffered crossbar based packet switches. The general case of a switch with M inputs and N outputs is considere
