FPGA-based Implementation of a Novel Cell-Search Algorithm for Mobile Communications
Current and future mobile communication networks rely on the cellular topology. The ability of a mobile user equipment (UE) such as a mobile phone to search for nearby cell towers and select the best available one to establish a connection is very crucial. At IIS, we have invented a new technique for the cell-search functionality in 3rd/4th generation mobile communication systems, which provides superior performance to known techniques. During the cell-search process, the mobile UE has to synchronize the local oscillator frequency relative to the carrier. Otherwise, the signal integrity is highly compromised and the overall performance is severely degraded.
To this end, the student will study and port the Matlab implementation of the algorithm to VHDL in order to implement the new technique on a powerful state-of-the-art FPGA board. After testing and verifying the hardware implementation, the VHDL code will be integrated with the rest of the already-implemented chip solution; thereby completing the whole baseband receiver chain.
