码片同步 ：指接收端的扩频码与发送端的扩频码在码片时序上的同步。这一过程需要解决码片时序的捕获和跟踪问题，通常采用滑动相关法、匹配滤波法等技术实现。
We offer our personal own perspectives and professional insights when examining and creating the phrases. Every expression consists of one of a kind info that you simply wouldn't obtain everywhere else online. That's why people world wide go on to come back to DevX for education and learning and insights.
With CDMA, signals that aren't correlated with the channel of fascination (including other PN offsets from adjacent cellular base stations) seem as sounds, and indicators carried on other Walsh codes (which might be adequately time aligned) are fundamentally taken off from the de-spreading method.
Every BTS dedicates an important number of output electric power into a pilot channel, that's an unmodulated PN sequence (Basically, spread with Walsh code 0). Every single BTS sector inside the network is assigned a PN offset in steps of 64 chips.
ISA-95 Element 7 defines know-how unbiased services and messages for associating and mapping aliases (equivalent identifiers) and affiliated context that are exchanged in between manufacturing operations area applications and applications in other domains.
