Abstract
In DS/SS receiver, correlation peak power is square of sine-function of Doppler shift. By taking this priori knowledge into account, the paper put forward a Doppler shift estimation algorithm using nonlinear least squares estimation method. Estimation performance was evaluated by computer simulation and compared with four-quadrant frequency discriminator algorithm (FQFD) used in GPS receivers.
