A rough guide to MIMO

Commercial radio technology has reached an inflection point similar to the transition from analogue to digital which created a range of new digital technology. Now we are moving from single carrier technologies, where we transmit one digital symbol at a time, to the point where we are potentially transmitting hundreds of […]

XMOS Semiconductor, a fabless semiconductor and software provider based in Bristol, United Kingdom, has developed the XS-1 family of what it calls Software-Defined Silicon (SDS) chips. BDTI expects that XMOS will announce its first chip, containing four 400 MHz 32-bit processor cores (each core is called a âEURoetile,âEUR� see figure below) at the Embedded Systems Conference […]
