ETAPS 2006 was once the 9th example of the ecu Joint meetings on thought and perform of software program. ETAPS is an annual federated convention that was once proven in 1998 via combining a few current and new meetings. This yr it comprised ? ve meetings (CC, ESOP, FASE, FOSSACS, TACAS), 18 satellite tv for pc workshops (AC- CAT, AVIS, CMCS, COCV, DCC, EAAI, FESCA, FRCSS, GT-VMT, LDTA, MBT, QAPL, SC, SLAP, SPIN, TERMGRAPH, WITS and WRLA), tutorials, and 7 invited lectures (not together with those who have been speci?

For a UWB system the pulses have a short t and very wide bandwidth B. 1. 1 Power spectral density of some common wireless broadcast and communication systems. 013 narrowband narrowband narrowband wideband ultra wideband The energy used to transmit a wireless signal is not infinite and, in general, should be as low as possible, especially for today’s consumer electronic devices. If we have a fixed amount of energy we can either transmit a great deal of energy density over a small bandwidth or a very small amount of energy density over a large bandwidth.

This equation will be familiar to anyone who has studied communication or information theory. Capacity is important as more demanding audio-visual applications require higher and higher bit rates. 1) where C is the maximum channel capacity, with units [bits/second]; B is the channel bandwidth [Hz]; S is the signal power in watts [W] and N is the noise power also in Watts. This equation tells us that there are three things that we can do to improve the capacity of the channel. We can increase the bandwidth, increase the signal power or decrease the noise.

7 PENETRATION CHARACTERISTICS One of the most important benefits of the UWB communication system that has been raised is the ability of pulses to easily penetrate walls, doors, partitions, and other objects in the home and office environment. In this section we will examine SPATIAL AND SPECTRAL CAPACITIES 19 the reported results for penetration of UWB pulses and comment on how that will affect communication in the home and office. Frequency f and wavelength λ are related by the speed of light c as is shown in the well-known Eqn.
