EE Times' Top 10 Design Features of 2009
The top ten EETimes design features of 2009 show the conflicts inherent with grip of C on embedded programmers, the popularity of teardowns and the need for further education, both on the basics as well as cutting-edge design issues such as HDMI/DVI handshaking.
Quantifying Gain Compression in RF Power Amplifiers: An Improved Method for OFDM Signals
Understand the challenges of this vital but complex measurement, and a way to achieve it.
Book Excerpt--Microwave and RF Design: A Systems Approach (Part 6 of 8)
Enhance your understanding of transmission lines and microstrip structures, in theory and practice
Myths and realities of real-time linux software systems
This paper addresses some of the differences between real-time and general operating systems including an analysis of several common misconceptions including performance issues, latency, hard vs. soft real-time systems, programming APIs and the software kernel.
Wireless triangulation using RSSI signals
Understand how a received signal strength indicator, combined with a networked quartet of transceivers and antennas, can pinpoint a transmitter's location
Tutorial: Tuning the baseband-to-radio connection for wireless basestations
The migration of advanced features to lower end mobile phones is challenging base station manufacturers to deliver new levels of performance. The Common Public Radio Interface (CPRI) spec is tuned to do exactly that.
How adaptive modulation can multiply link capacity in carrier Ethernet over wireless
By utilizing the infrequently used fade margin (the difference between the instantaneous receiver level and the equipment receiver threshold) adaptive modulation can dramatically increase link capacity at little or no additional cost.
Endgame: Will WiMax and LTE find happiness in multimode?
LTE and WiMax may be two peas in an OFDM pod, but they are not twins. Harmonizing the contenders in orthogonal frequency-division multiplex standards before silicon would have distinct advantages, not the least of which is power consumption.
