Table 3 Approximated theoretical tracking jitters of CAT, DBT and DMT methods in carrier, subcarrier, coherent code and non-coherent code tracking loops
Methods | PLL | SPLL | Coherent DLL | Non-coherent DLL |
|---|---|---|---|---|
CAT | \(R\sigma _o\) | \(2R\sigma _s\) | \(R\sigma _{c,{\textrm{coh}}}\) | \(R\sigma _{c,{\textrm{noncoh}}}\) |
DBT | \(\frac{R}{\sqrt{2}} \sigma _o \) | \(\sqrt{2}R\sigma _s\) | \(\frac{R}{\sqrt{2}} \sigma _{c,{\textrm{coh}}}\) | \(\frac{R}{\sqrt{2}} \sigma _{c,{\textrm{noncoh}}}\) |
DMT | \(\sigma _o\) | \(\sigma _s\) | \(\sigma _{c,{\textrm{coh}}}\) | \(\sigma _{c,{\textrm{noncoh}}}\) |
