Signal processing optimisation for
networks
Wireless Local Area Network (WLAN) and home Audio/Visual (A/V) network technologies are increasingly seeking to reach high data rate wireless communications
Kane Computing (KCL) has announced the launch of Lyrtech's Quad Dual-Band RF Transceiver as part of a solution dedicated at developing and optimising the signal processing capabilities of Multiple Input Multiple Output (MIMO) systems operating in the 2.4-5 GHz bands (WiFi, 2.4Ghz ISM, etc.) Today's emerging Wireless Local Area Network (WLAN) and home Audio/Visual (A/V) network technologies are increasingly seeking to reach high data rate wireless communications

Video images converted without framegrabbers
Analogue to digital video converters capture and convert NTSC/PAL video into digital images, then transfer them to a host computer, eliminating the need for plug-in framegrabbers.
Framegrabbers integrated into embedded systems
Real time image capture can easily be integrated into an embedded system. Support for Windows 95/98/200/N, VxWorks (x86) and Linux/RT Linux is provided.
This demand for higher access speeds constitutes a significant research and engineering challenge.
It is in such a context that the Institute of Electrical and Electronics Engineers (IEEE) and the International Telecommunications Union (ITU) are undertaking efforts to integrate MIMO technologies to overcome such a challenge.
Lyrtech's Quad Dual-Band RF Transceiver offers a complete MIMO transceiver and a powerful conversion and signal processing solution as a rise to the challenge.

Ultra fast cameraLink digital video acquisition and real-time processing boards offers real-time pre-processing of the video data.
Converter avoids framegrabber
For people who want to stream analogue NTSC/PAL video into PCs and laptops, where plugging in a framegrabber is not possible or not preferred, a converter does the job.
Superior solution offered for protocol stack
A superior solution is being offered for implementing Internet connectivity in embedded applications based on Texas Instruments' TMS320 DSP: the bf3Net TCP/IP protocol stack.
The Quad Dual-Band RF Transceiver is a four-channel MIMO RF analog front end, designed under an exclusive partnership with COMLAB, as a companion to the Lyrtech VHS- ADC DAC Virtex-4 family of advanced development platforms, which provides the analog-to-digital-to-analog multi-channel conversion interface and digital signal processing capabilities.
When combined with additional DSP/FPGA processing boards, such as the SignalMaster Quad Virtex-4, it becomes a complete and very high performance MIMO RF development system.
"The integration of Lyrtech's signal processing products with ComLab's Quad Dual-Band RF Transceiver creates a unique solution that is ideal for key applications such as MIMO advanced base stations, multi-antennas systems, adaptive beamformers, wireless routers and multi-channel analysis," says Benoit Fleury, Vice President Sales and Marketing, Lyrtech.
Single-transmit single-receive antenna wireless systems can reach 1 Gbps transmission rates but face other limitations associated with the various phenomena that occur not only in WLAN and A/V but also in outdoor Wireless Wide Area Networks (WWAN).
For example, the phenomenon known as fading, which consists on random fluctuations in signal level on non-line-of-sight propagation, is resolved by advanced MIMO systems such as the Quad Dual-Band RF Transceiver.
A MIMO advanced base station takes advantage of interference and multi-path phenomena by using multiple antennas to send multiple parallel signals from a single transmitter.
In an urban environment, these signals will encounter interference such as trees and buildings.
The signals will bounce off the object and continue on their way to the receiver but from different directions.
Multi-path occurs when the signals arrive at the receiver at various times.
With MIMO, the receiving end uses an algorithm or special signal processing to sort out the multiple signals to produce one signal that embodies the originally transmitted data.
The main advantages of the MIMO technology are reduced costs, a better experience for the mobile user (moving at speeds of up to 125 km/h ), as well as greater bandwidth, reach and spectral efficiency than the alternative antenna technology. Request a free brochure from Kane Computing ...
