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 Nfft.
void modulate (const cvec &input, cvec &output)
 Modulate complex data symbols. Length of input must be Nfft.
cvec demodulate (const cvec &input)
 Demodulate to complex valued symbols. Length of input must be Nfft+Ncp.
void demodulate (const cvec &input, cvec &output)
 Demodulate to complex valued symbols. Length of input must be Nfft+Ncp.

Detailed Description

Class for modulating and demodulation of OFDM signals using the FFT.
