Public Member Functions | |
OFDM (void) | |
Empty constructor. | |
OFDM (int inNfft, int inNcp, int inNupsample=1) | |
Constructor Nfft is the size of the FFT. Ncp is the length of the cyclic prefix. Nupsample is the upsampling factor (default=1) | |
int | no_carriers () |
Return the number of carriers. | |
void | set_parameters (const int Nfft, const int Ncp, const int inNupsample=1) |
Set parameters. | |
cvec | modulate (const cvec &input) |
Modulate complex data symbols. Length of input must be an integer multiple of Nfft . | |
void | modulate (const cvec &input, cvec &output) |
Modulate complex data symbols. Length of input must be an integer multiple of Nfft . | |
cvec | demodulate (const cvec &input) |
Demodulate to complex valued symbols. Length of input must be an integer multiple of Nfft+Ncp . | |
void | demodulate (const cvec &input, cvec &output) |
Demodulate to complex valued symbols. Length of input must be an integer multiple of Nfft+Ncp . | |
Class for modulating and demodulation of OFDM signals using the FFT.
The modulated signal is normalized taking into account the cyclic prefix
