% PREPROCESSSIGNAL Performs standard preprocessing on a signal
%
% Inputs:
%   Scpe_sig - Input signal
%   Symbols - Reference symbols for synchronization
%   fsym - Symbol frequency
%
% Outputs:
%   Scpe_sig - Preprocessed signal

% Resample to 2x symbol rate
Scpe_sig = Scpe_sig.resample("fs_out", 2*fsym);

% Synchronize with reference
[Scpe_sig, ~] = Scpe_sig.tsynch("reference", Symbols, "fs_ref", fsym, "debug_plots", 0);

% Apply Gaussian filter
% Scpe_sig = Filter('filtdegree', 4, "f_cutoff", Symbols.fs.*0.6, ...
%                  "fs", Scpe_sig.fs, "filterType", filtertypes.gaussian, ...
%                  "active", true).process(Scpe_sig);

% Remove DC offset
