Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...

Wide area wireless networks will have limited bandwidth. One standard approach for increasing the eeective throughput on such links is to employ data compression. In conjunction with any data compression supplied by applications, low{bandwidth systems may also use hardware data compression provided by the data communications device. Unfortunately, compression at such a low level can cause probl...

Since the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, instead of an ensemble of an n–D realization. Although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to better results. In this paper, first a method is prop...

Bandwidth management is a generic term that describes the various techniques, technologies, tools and policies employed by an organization to enable the most efficient use of its bandwidth resources „Efficient use‟ means both the minimization of unnecessary bandwidth consumption and the delivery of the best possible levels of service to users.‟ Bandwidth resources‟ refers to the bandwidth of a ...

Subject terms: electro-holography, holographic computation, holographic bandwidth compression, diffractionspecific, fringelet, hogel vector Abstract. A novel electro-holographic bandwidth compression technique, fringelet bandwidth compression, is described and implemented. This technique uses spatial subsampling to reduce the bandwidth and complexity of holographic fringe computation for real-t...

To enable ubiquitous wireless multimedia communication, the bottlenecks to communicating multimedia data over wireless channels must be addressed. Two significant bottlenecks which need to be overcome are the bandwidth and energy consumption requirements for mobile multimedia communication. In this paper, we address the bandwidth and energy dissipation bottlenecks by adapting image compression ...
