AbstractWe propose an advanced GPS solution for software defined radios (SDR) for military users. Different from conventional software GPS receivers that merely mimics what a hardware receiver does, the proposed GPS solution sets forth advanced signal processing techniques along the signal and data processing chain, some of which are difficult, if not impossible, to implement within conventional receiver architectures, thus allowing the realization of the full potential a software receiver can possibly offer. For military applications, the design emphases are therefore placed on dynamic range, interference suppression, and weak signal operations. In the Phase I base effort, the proposed algorithms will be formulated and a subset of which will be investigated for implementation within the Software Communications Architecture (SCA). In the Phase I option effort, the design of a hardware accelerator will be conducted to implement a cascaded DFT/IDFT on FPGA. In Phase II, the validated algorithms and their designs will be prototyped for demonstration.
