Trading pieces: IP market grows, but slowly

- BY GRAHAM PROPHET • EDITOR
THE MARKET IN TRADED IP FOR INCLUSION INTO SYSTEM-ON-SILICON CHIPS UNDERPINS MANY OF TODAY’S LARGEST DESIGNS. IT’S NOT THE VIBRANT BAZAAR THAT ITS PROPONENTS ONCE ENVISAGED, BUT THE MECHANISMS FOR IP EXCHANGE ARE EVOLVING, AS WAS EVIDENT AT THE IP07 CONFERENCE IN GRENOBLE.

Spectrograms reveal mobile-WiMAX-zone structure

- BY BEN ZARLINGO • AGILENT TECHNOLOGIES
THE MOBILE WiMAX PHYSICAL-LAYER SIGNAL CONTAINS FAR MORE INFORMATION AND IS CONSIDERABLY MORE COMPLEX THAN TRADITIONAL SINGLE-CARRIER MODULATION SCHEMES, MAKING IT HARD FOR CONVENTIONAL SPECTRUM ANALYSIS TO REVEAL THE UNIQUE CHARACTERISTICS OF THIS DYNAMIC WAVEFORM: HOWEVER, THE SPECTROGRAM PROVIDES A MEANS OF INTERPRETING THE SIGNAL STRUCTURE.

Coding SPI software
