Radio channel simulation (noise, phase error, frequency error, ...)
prm = chn_simu_prm();
Resulting structure defining the channel parameters.
This function enables to initialize the field of a structure defining which distortions to use when simulating a radio propagation channel with the chn_simu function. By default, all channel distortions are disabled. One can activate them selectivly by modifying the following fields:
prm.sigma_wn
= standard deviation of the white noise.prm.delta_t
= timing offset between receiver and transmitter clock (in samples).prm.freq_offset
= frequency offset (compared to expected carrier frequency).prm.phase_offset
= carrier phase offset (in radians).
