A reduced complexity frequency domain acquisition of DS-SS signals for embedded applications

AbstractIn this paper we propose an efficient algorithm to compute low-rank approximation to the solution of so-called “Laplace-like” linear systems. The idea is to transform the problem into the frequency domain, and then use cross approximation. In this case, we do not need to form explicit approximation to the inverse operator, and can approximate the solution directly, which leads to reduced complexity. We demonstrate that our method is fast and robust by using it as a solver inside Uzawa iterative method for solving the Stokes problem.

Domain Acquisition

An acquisition and tracing algorithm of GPS receiver is introduced. The shortage of time domain acquisition algorithm is pointed out by analyzing the composition of GPS signal and C/A code’s correlation property. Then the frequency domain acquisition algorithm is discussed. The carrier wave track loop and C/A code track loop are designed and the algorithms of them are determined. Using these two loops can get the navigation message, etc that used for positioning and navigation. The GPS raw intermediate data is processed and the satellites signals are acquired and traced in MATLAB, then obtain the navigation message verified the feasibility and availability of the acquisition and tracing algorithm.
