Creation of a modulator object
mod = mod_init(name,fs,fi,fsymb[,mode]) mod = mod_init(wf,fs,fi,fsymb[,mode])
Waveform name ('bpsk', 'qpsk', 'qam16', ...: same parameter as wf_init)
Waveform object (created with wf_init)
Output sample frequency (in Hz)
Output intermediate (or RF) frequency (in Hz)
Symbol frequency (in Hz)
Real modulation ('r') or I/Q modulation ('c'). Default is real modulation.
In the first form, the default waveform configuration is used (NRZ pulse shaping, and default waveform parameters). In the second form, the user can configure more accurately the waveform.
