Title:
スペクトル拡散信号受信装置
Document Type and Number:
Japanese Patent JP7055565
Kind Code:
B2
Abstract:
To provide a spectrum spread signal receiver with which it is possible to appropriately search in a short time for the code phase of a spectrum spread signal consisting of a time-division multiplexed L2C or L6 signal.SOLUTION: When correlation processing an L2C signal and a replica code using a correlator and searching for a code phase, a GNSS signal receiver having received the L2C signal in which an L2CM code and an L2CL code are time-division multiplexed, uses the L2CM code for the replica code in an L2CM code section, and continues using the L2CM code for the replica code in some initial portion of an L2CL code section and does not perform correlation processing in the rest of the section.SELECTED DRAWING: Figure 3
