cvec SIM::cofdm_mod::get_carriers

(

)

get carriers - modulator input QAM|BPSK [I+jQ]

Returns

- [cvec] complex carriers

int SIM::cofdm_mod::get_CP

(

)

get CP size

Returns

- [int] CP size

int SIM::cofdm_mod::get_NFFT

(

cvec SIM::cofdm_mod::get_symbol

(

)

get symbol - by setting new modulator output - complex time domain symbol y0=[CP|INV_FFT(carriers)]

Returns

- [cvec] y0

cmat SIM::cofdm_mod::process	(	const bvec &	ce,
		const cmat &	x
	)

for active clock ticks ce[i] and for QAM,BPSK carriers x[i,:] return time domain cofdm symbol y[i,:].

Parameters

ce	- bvec[:] - clock_enable vector,
x	- cmat[:,NFFT] - QAM, BPSK carriers matrix,

Returns

y - cmat[:,NFFT+CP] - cofdm symbols matrix.
