这是GPS接收机，基带处理模块中CA码产生模块设计代码，用于码跟踪环。代码设计巧妙，采用了后台机配合的方式，可以灵活产生各卫星的PN码，节约了触发器资源-This is the GPS receiver, Baseband Processing Module CA code generator module design code for the code tracking loop. Code so cleverly designed and adopted a background with the plane, the flexibility to produce satellites PN code, saving resources Trigger
