DVB-T/DVB-H demodulator

Overview

A highly configurable DVB-T demodulator core suitable for a wide-range of applications included test, measurement and broadcast montioring equipment. Our core provides the DVB-T(H) extensions which when combined with the superior performance offered by our inter-carrier-interferance cancellation algorithm make this core ideally suited for mobile environments.

The flexibility of the core provides for application-specific optimisations not found within tradational off-the-shelf offerings, such as low symbol rates and reduced number of COFDM subcarriers for low-bandwidth applications.
