DAB receiver test methods

It was being proposed that DAB receivers should carry some form of certification mark, to indicate an acceptable level of performance.  To allow such a scheme, it was necessary to develop a robust and repeatable method for receiver sensitivity testing.  This study compared the sensitivity measurements obtained using two different test methods – one using[…]

Spectrum efficiency of analogue and digital wireless microphones

The study sought to quantify the relative and absolute spectrum efficiency of digital and analogue wireless microphones.  It was required in the context of the general background of reduced availability of UHF spectrum for PMSE use, and the specific requirement to ensure adequate spectrum resources for the London Olympics in 2012.   The study considered examples[…]
