Transceiver Design Concept for Cellular and Multispot Diffusing Regimes of Transmission
A number of attempts have been made in an effort to combine the advantages of line-of-sight and diffuse configurations for indoor optical wireless communications via sophisticated combinations of elements that are characteristic for these architectures. A different approach has been followed in the present investigation, namely, developing a transceiver capable of operating in both configuratio...
متن کاملmixed signal Transceiver
www.rfdesign.com February 2001 I today’s world of miniaturization, there is everincreasing industry pressure to reduce the cost of communication chips. This pressure has driven designers to develop transceivers with higher levels of integration1. Achieving the goal of maximum integration between the antenna and data output is not as trivial as replacing external components with on-chip componen...
متن کاملGigahertz optical spin transceiver.
We present a time-resolved optical technique to measure electron spin dynamics with GHz dynamical bandwidth, transform-limited spectral selectivity, and phase-sensitive (lock-in) detection. Use of a continuous-wave (CW) laser and fast optical bridge enables greatly improved signal-to-noise characteristics compared to traditional optical sampling (pump-probe) techniques. We demonstrate the techn...
متن کاملUltra-Wideband RF Transceiver
Where, C is the channel capacity, BW is the bandwidth, SNR is the ratio of average received signal power to the noise spectral density. It can be seen from (1), channel capacity increases linearly with bandwidth but only logarithmically with SNR which means capacity increases as a function of BW faster than as a function of SNR and with a wide bandwidth, high data rate can be achieved with a lo...
متن کاملRandom transceiver networks
Consider randomly scattered radio transceivers in Rd, each of which can transmit signals to all transceivers in a given randomly chosen region about itself. If a signal is retransmitted by every transceiver that receives it, under what circumstances will a signal propagate to a large distance from its starting point? Put more formally, place points {xi} in Rd according to a Poisson process with...
