Synchronization

PURPOSE ^

Synchronization of the received signal.

SYNOPSIS ^

function [ r_corrected, Delta_tau_hat, Delta_omega_hat ] = Synchronization( r, Para, d_TR )

DESCRIPTION ^

 Synchronization of the received signal.

 function [ r_corrected, Delta_tau_hat, Delta_omega_hat ] = Synchronization( r, Para )
 function [ r_corrected, Delta_tau_hat, Delta_omega_hat ] = Synchronization( r, Para, d_TR )

 The function works for SISO systems.

 Input arguments:

   r: received signal. Size: vector [1, nFrameSamples].

   Para: structure containing the modulation parameters.

   d_TR: mandatory for FBMC-OQAM, vector [Para.nSubcarriers, 1] of pilot symbols.

 Outputs arguments:

   r_corrected: received corrected signal. Size: vector [1, ~]

   Delta_tau_hat: estimated STO [sampling periods].

   Delta_omega_hat: estimated CFO [rad/s].

 See also OFDM_Synchronization, FBMC_OQAM_Synchronization.

CROSS-REFERENCE INFORMATION ^
