AbstractThe B1C signal adopts a new navigation signal system including pilot and data signal. These two signals are transmitted simultaneously in an orthogonal manner. When the signal is weak, two signals need to be processed jointly to improve the signal detection ability. This paper designs a novel weighted joint acquisition algorithm. Monte Carlo simulation has been done to evaluate the performance. The simulation results show that the detection performance of the proposed algorithm connects with the weighted coefficient. When the optimal weighting coefficient is selected, detection performance can be improved greatly under the condition of weak signal. Keywords: B1C signal, weighted joint acquisition algorithm, weighted coefficient.
