Interferences can significantly degrade the performance of global navigation satellite system (GNSS) receivers. Therefore, mitigation methods are required to ensure reliable operations. However, as there are different types of interferences, robust, multi-purpose mitigation algorithms are needed. The high-rate DFT-based data manipulator (HDDM) algorithm is a promising mitigation method, but so far has only been evaluated in theory and software. This paper presents a hardware implementation of the HDDM algorithm and its evaluation in an exemplary hardware configuration with comparison to the interference mitigation of a high-end professional receiver. Results with interferences achieve the same or improved performance. With more complex interferences, like frequency hopping or pulsed, the HDDM shows even better performance than state of the art.
