Folasaga

I le fa'asalalau uaealesi, o le Transmitter (Tx) ma le Receiver (Rx) e tu'u'ese'ese i se mamao ma fa'amama eletise. E ui lava o le Tx ma le Rx o loʻo faʻalogo i le taimi tutusa, o loʻo i ai se faʻalavelave faʻafuaseʻi i le va o laina vaʻavaʻa ona o le eseesega o le ppm i le va o oscillators faʻaaogaina i Tx ma Rx. O le fa'asologa o taimi e totogi e ala i le fa'aogaina o fa'amatalaga fesoasoani po'o le leai o fa'amatalaga (tauaso) fa'atasi.

O le Costas Loop o se auala e le fa'aogaina e le PLL e fa'atatau i fa'amatalaga mo le fa'asolo taimi fa'ase'ese taui. O le fa'aoga muamua o fa'amaufa'ailoga a Costas o lo'o i totonu o fa'aeleele e maua. I le faʻaaogaina o lenei mea, o le faʻasologa o taimi i le va o le Tx ma le Rx e totogi e aunoa ma le fesoasoani a leo pailate poʻo faʻailoga. O le Costas Loop o loʻo faʻatinoina mo le BPSK ma le QPSK modulations faʻatasi ai ma se suiga i le poloka faʻatatau mea sese.
