demod_init
Initialization of a demodulator object.
Calling sequence
demod = demod_init(name,fs,fi,fsymb)
demod = demod_init(wf,fs,fi,fsymb)
demod = demod_init(name,fs,fi,fsymb) demod = demod_init(wf,fs,fi,fsymb)
Parameters
- name:
classical waveform name ('bpsk', 'qpsk', 'qam16', ...)
- wf:
Waveform object (created with wf_init)
- fs:
Input sample frequency
- fi:
Intermediate (or RF) frequency
- fsymb:
Symbol frequency
classical waveform name ('bpsk', 'qpsk', 'qam16', ...)
Waveform object (created with wf_init)
Input sample frequency
Intermediate (or RF) frequency
Symbol frequency
Examples
// QPSK demodulator (NRZ matched filter),
// sampling frequency = 1 MHz, IF = 200 KHz, FSYMB = 20 KHz
demod = demod_init('qpsk', 1e6, 200e3, 20e3);
// QPSK demodulator (NRZ matched filter), // sampling frequency = 1 MHz, IF = 200 KHz, FSYMB = 20 KHz demod = demod_init('qpsk', 1e6, 200e3, 20e3); |
