Maozhong Song · Shuju caiji yu chuli · 2003
Some researches about joint-estimation of pseudo-random code tracking and separation of sub-chip multipath components are carried out in presence of multipath interference for providing a feasible scheme. First, traditional code tracking theory is analyzed to be not applicable in multipath environment. Secondly, multipath channel pulse response is estimated without taking channel noise into account, and this kind of joint-estimation is realized, which is combined with a simple new algorithm for extracting multipath components. Finally, simulational results are demonstrated. Additionally, projection on convex sets (POCS) deconvolution technique is applied for integrality of the whole scheme.
