Software defined radio implementing GPS parallel frequency space search acquisition algorithm in real time environment

In this paper, a parallel frequency space search acquisition algorithm for a GPS (Global Positioning System) receiver is implemented using software defined radio (SDR) technology. The proposed algorithm is implemented and tested using National Instruments MyRio real time software processor platform. The results of the proposed algorithm are confirmed and compared with the parallel code phase search algorithm using different implementation platforms. The parallel frequency search implementation is highly recommended for real time and high speed seamless applications in product development and industry platforms where low cost, low complexity with reliable performance is of dire need. The novelty of this approach stands as no published literature has demonstrated parallel frequency search algorithm as an SDR platform using National Instruments Labview on MyRio real time processor environment. In this research, parallel frequency space acquisition of GPS signals on an NI myRio device is implemented. The parallel frequency acquisition is selected because of its moderate code acquisition complexity and its better resource management compared to parallel code phase algorithm, which is considered a large resource consumer.
