An advanced Global-Navigation-Satellite-System (GNSS) accelerator, which provides the end user with improved position, velocity and time solutions. High performance conventional GPS/GNSS receivers rely on ASIC technology to implement massive correlators, as the performance of SDR solutions is still limited. With a reasonable distribution of tasks between the host hardware and reconfigurable peripherals, a higher performance is achieved. The figure illustrates a schematic structure of a GNSS receiver, where the proposed... -
Memristors are resistive devices with varying resistance which depends on the voltage applied to the device. The most natural memristor application is memory. However memristors can also be used for other applications, for example logic circuits. Once such approach is MRL (Memristor Ratioed Logic) - a hybrid CMOS-memristive logic family. In MRL, OR and AND logic gates are designed using memristors. The limitation of MRL is that every memristor-based logic... -
Edge and feature extraction is one of the most important first steps in computer vision. Its main objective is to find as many useful features from a scene while keeping the output noise level to a minimum. Edge, corner and vertex detection processes serve to simplify the analysis of images by drastically reducing the amount of data to be processed. The SUSAN principle is the basis for algorithms to perform...

Orthogonal Frequency Division Multiplexing (OFDM) is a Frequency Division Multiplexing (FDM) technique used as a digital multi-carrier modulation method. Instead of using one high speed channel, the data is split into a large number of lower speed channels. Orthogonal sub carriers are used to carry data on several parallel data streams which allows more efficient use of the spectrum compare to regular FDM. Orthogonality of the carriers prevents interference between...
