| class | gr_quadrature_demod_cf |
| quadrature demodulator: complex in, float outThis can be used to demod FM, FSK, GMSK, etc. The input is complex baseband. More... | |
| class | digital_ofdm_frame_acquisition |
| take a vector of complex constellation points in from an FFT and performs a correlation and equalization.This block takes the output of an FFT of a received OFDM symbol and finds the start of a frame based on two known symbols. It also looks at the surrounding bins in the FFT output for the correlation in case there is a large frequency shift in the data. This block assumes that the fine frequency shift has already been corrected and that the samples fall in the middle of one FFT bin. More... | |
