Imec unveils single-chip reconfigurable digital radio front-end
Imec presented a digital front-end component for low-cost and low-power spectrum sensing, paving the way to power-efficient cognitive radios and networks. While current radio architectures are focused on the reception of a predefined channel, and cannot proceed to a frequency scan operation in a timely, cost- and energy-effective way, Imec’s cognitive reconfigurable radio solutions enable multi-mode communication and spectrum sensing.

Imec’s new spectrum sensing component was designed as a versatile digital engine to meet a wide variety of use cases, at low cost and low power overhead. The chip, which hosts a dedicated application-specific integrated processor, can perform both flexible synchronization and spectrum sensing for high-throughput WLAN (802.11a-n), cellular standards (including the recent 3GPP-LTE), and digital broadcasting standards.

The spectrum sensing component connects to imec’s in-house designed analog reconfigurable radio chip (SCALDIO) and imec’s programmable digital baseband platform conceived for 4G seamless connectivity (COBRA). As such, imec’s complete reconfigurable radio solutions enable multimode communication with efficient use of the spectrum.
