摘要
Abstract
L2P(Y) signal tracking in dual-frequency receiver can be implemented by employing semi-codeless method. However,the actual L2P(Y) signal earner to noise ratio is very low due to squaring-loss. As a result, higher performance requirements are needed for L2P(Y) signal tracking loop. This paper presents a way of using dynamic-aided L2P( Y) tracking. Loop design details are given,and the various factors affecting the performance of the loop are discussed in detail. The performances of the dynamic-aided loop and the none-aided loop are compared through computer simulation. Simulation results show that dynamic-aided method can track L2P(Y) signal in lower carrier to noise ratios effectively.关键词
