Early-late gate

WebAn early-late gate symbol synchronizer can easily be implemented, but you'll need to first run the data through a matched filter, which will require at least an estimate of the symbol rate. ... If the local clock is early or late, the natural PLL action is to adjust the VCO frequency just a bit. Eventually lock is achieved at a multiple of the ... WebNov 30, 2008 · Abstract: Because of the multi-peak auto-correlation function, false locking may happen in Galileo BOC code tracking process. Firstly, the shortcoming of the classic early-late-gate tracking loop for BOC code tacking is discussed. Then, new tracking loops which combined multi-early-late-gates are designed in this paper to remove the …
