Carriers Test Spectrum Sharing with U.S. DoD

 AT&T, Verizon and T-Mobile USA will begin testing the viability of sharing 95 MHz of spectrum that is currently used by U.S. Department of Defense (DoD) and other federal agencies. Last year, the National Telecommunications and Information Administration (NTIA) proposed a spectrum sharing scheme between government and industry.  Specifically, the NTIA determined that 95 megahertz (MHz) of prime spectrum in the 1755 – 1850 MHz band...

Fujitsu's Vector Processing DSP Promises LTE Performance Gains

Fujitsu Laboratories has developed a digital signal processor (DSP) for mobile device baseband processing that uses the same vector processing architecture employed in supercomputers. Fujitsu's 28-nanometer DSP runs at 250 MHz and is  capable of processing data at 12 GOPS (12 billion operations per second). Excluding memory, the DSP measures only 0.4 mm2, and it consumes 30 milliwatts (mW) of power, 20% less than existing DSPs. It can run...
