function [sim_param,DANSE_param] = gen_param(source_sig,noise_sig)
% GEN_PARAM - generate simulation and DANSE parameters
% Syntax:  [] = frame_signal(node,sim_param)
% generates frames of data for batch algorithms
% Inputs:   source_sig      -   desired source signal (can be multichannel)
%           noise_sig       -   additive noise (can be multichannel)
%
% Outputs:  DANSE_param     -   structure with DANSE parameters
%           sim_param       -   structure with simulation parameters
%
% Other m-files: none
