Barry level and for less difficult introductions to the subject the books on the spectra of simple free radicals (Herzberg, 1971) and on flame spectroscopy by Mavrodineanu and Boiteux (1965) may be better. The book on Dissociation Energies (Gaydon, 1968) gives a rather similar treatment to that presented here but with some more detail.作者: FLAGR 時間: 2025-3-22 01:10 作者: Humble 時間: 2025-3-22 04:51 作者: 孵卵器 時間: 2025-3-22 10:04

Modeling Multipath Dispersion,f the technique. We present computer simulation results for both line-of-sight and diffuse transmitter configurations..both cases we find that reflections of multiple order are a significant source of intersymbol interference. We also describe experimental measurements of optical multipath, which help verify the accuracy of our simulations.作者: 可憎 時間: 2025-3-25 02:50 作者: Phenothiazines 時間: 2025-3-25 04:43
Introduction,rom room to room will have access to the same high-speed network services available to wired terminals. The technology base for implementing this concept does not yet exist, however. Radio technology, although well-suited for moderate-speed applications such as voice, may not be sufficient to support many high-speed applications.作者: 桶去微染 時間: 2025-3-25 10:04
System-Level Issues,rared links as building blocks for a wireless LAN. Because a complete design of a wireless LAN is beyond the scope of this book, the discussion presented here will not be in depth; nevertheless, it should convince the reader that there are no fatal obstacles to an infrared LAN lurking in the higher network layers.作者: 吹牛者 時間: 2025-3-25 15:18 作者: Obligatory 時間: 2025-3-25 16:33 作者: GEN 時間: 2025-3-25 22:05 作者: jaundiced 時間: 2025-3-26 00:49
Receiver Design, a low-noise, wide-band preamplifier. The design of the preamplifier is challenging due to the high capacitance of large-area photodiodes and a potentially intense background light. The error performance of the entire system depends to a large degree on the ability of the preamplifier to amplify the作者: 車床 時間: 2025-3-26 08:03
Modeling Multipath Dispersion,ter investigates the properties of the wireless infrared channel itself, over which the designer has no control. Specifically, we examine the severity of multipath dispersion in typical indoor environments, and assess its effect on system performance.

We review the unique characteristics of the intensity-modulation channel, which differs from a conventional linear Gaussian-noise channel in two ways: the input cannot be negative, and the average amplitude — not power — of the input is limited.

Conclusions and Future Work,eeds near 100 Mb/s are practical. The only true test of this hypothesis, of course, is to build such a link and verify it experimentally. Researchers at the University of California at Berkeley are currently developing a 50-Mb/s prototype that incorporates many of the ideas in this book.
