With UWB uptake slow, Bluetooth hops on Wi-Fi News & Analysis 2/11/2008 Post a comment The Bluetooth Special Interest Group will provide a mechanism to let its protocol to ride on top of 802.11 networks while its longer term plan to create a version 3.0 based on ultrawideband technology moves slowly forward, a recognition of the market's rapid adoption of .11n and the relative slowness of UWB to gain traction.
DVB-H/T receiver housed in 5-mm x 5-mm CSP package Product News 2/11/2008 Post a comment Abilis' digital mobile TV receiver integrates a multi-band RF tuner, advanced OFDM demodulator, memory and interfaces onto a single 90nm CMOS die, with the receiver performance surpassing the MBRAI 2 and Nordig 1.0.3 specifications.
Xilinx, Freescale demo DPD design for efficient PA's Product News 2/11/2008 Post a comment Xilinx Inc. is demonstrating a digital pre-distortion (DPD) based reference design based on its Virtex range of FPGAs and XtremeDSPs that is optimized for Freescale Semiconductor's LDMOS power amplifiers at this week's World Mobile Congress in Barcelona, Spain.
The companies say the deisgn could significantly reduce development time and both capital and operational expenditure of wireless infrastructure.
The Road to WiMAX TV Design How-To 2/6/2008 Post a comment Mobile operators are finding that broadcast programming is the key to thriving in an increasingly competitive landscape. As growth rates from pure voice traffic flatten, they are introducing data applications, not the least of which are videos of popular broadcast network programs. Hence "mobile TV" is already proving to be a promising ARPU generator for mobile operators, with several million subscribers to such services worldwide.
Implementing OFDM modulation for wireless communications Design How-To 2/5/2008 Post a comment This article discusses various implementation schemes for orthogonal frequency division multiplexing (OFDM) modulation and demodulation. The focus of the article is cyclic prefix (CP) insertion and removal. The methods proposed use the Altera fast Fourier transform (FFT) MegaCore function.
What's in an RF Front End? Design How-To 2/4/2008 1 comment If you ever needed to explain what an RF front end is, part one of this series on RF Front End design gets the job done for you.
PicoChip, MimoOn team for LTE ref design Product News 2/4/2008 Post a comment picoChip has teamed with MimoOn (Duisburg, Germany), a start-up focusing on IP for MIMO technologies, for an end-to-end LTE reference design.
The companies plan to demonstrate the platform, which shares many commonalities with WiMAX designs, at next week's Mobile World Congress in Barcelona, Spain.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
