Abstract
A new conic fitting code discriminator is proposed for the traditional discriminator gain decreasing in bandwidth-limited environment. According to the correlation property, conic fitting code discriminator gets the conic equation with the early and late integration-dumping results. The code phase estimate can be calculated by solving equation. Simulation results show that the conic fitting code discriminator is not influenced by bandwidth and it has better discriminate performance than traditional discriminator when the system bandwidth is limited.
