Infrared Wireless Communications using Complementary Sequence
The performance of an infrared wireless system using direct sequence spread spectrum techniques in multipath channels depends very much on the partial correlation properties of the spreading sequences used. Ideally, a spreading sequence should have zero sidelobes in its periodic and aperiodic auto-correlation functions in order to eliminate multipath dispersion. Unfortunately, no such ideal seq...
متن کاملWireless Infrared Communications - Proceedings of the IEEE
The use of infrared radiation as a medium for high-speed, short-range wireless digital communication is discussed. Currently available infrared links and local-area networks are described. Advantages and drawbacks of the infrared medium are compared to those of radio and microwave media. Physical characteristics of infrared channels using intensity modulation with direct detection (IM/DD) are p...
متن کاملLink design for nondirected wireless infrared communications.
We optimize the design of a short-range communication system using nondirected line-of-sight IR radiation. We propose a receiver structure comprising a spherical thin-film optical filter and a truncated spherical lens that can significantly outperform an optimized planar-filter system. We can make the passband of the spherical filter arbitrarily narrow without constraining the field of view by ...
متن کاملPerformance modelling of the IrDA infrared wireless communications protocol
We present a performance analysis of the Infrared Data Association (IrDA) IR data communications protocol using a mathematical throughput model based on the virtual transmission time of uni-directional IrDA data packets. The IrDA standard speci"es a protocol stack for reliable short-range indoor IR wireless data communication between devices with the data link layer (IrLAP) being a HDLC derivat...
متن کاملChannel reuse strategies for indoor infrared wireless communications
We examine systems of fixed-channel reuse for base stations in an indoor infrared wireless communication system. The following techniques are compared: • time-division multiple access (TDMA) using on-off keying (OOK) or pulse-position modulation (PPM); • frequency-division multiple access (FDMA) using binary phase-shift keying (BPSK) or quadrature phase-shift keying (QPSK); • code-division mult...
