Pulse position modulation (PPM) has the advantages of low transmitting power and better anti-noise performance and has been used to be an attractive option for optical wireless communications. However, the limitation in low bandwidth utilization makes the PPM modulation de-efficiency for a large amount of data transmission, e.g. multimedia information. In this paper, we proposed and demonstrated a...
In this paper, we study bandwidth management of a wireless/optical based access/metro network in support of voice and data services. For voice services, we use a finite state Markov Chain to estimate the blocking probability of voice circuits over an Adaptive modulation and coding wireless channel, as a function of the channel parameters. For data services, we evaluate a rate matching and a buffer...
