Member Function Documentation

cvec SIM::cofdm_map::get_carriers

(

)

get COFDM carriers - QAM data carriers [I+jQ], pilots [+/-PA+j0], zero [0+j0] set by set_data() and set_pilots()

Returns

- [cvec] y0

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

for active clock ticks ce[i] and for [PILOT|DATA] codes x[i,:] return QAM, BPSK carriers y[i,:].

Parameters

ce	- bvec[:] - clock enable vector,
x	- imat[:,PILOT|DATA] - symbol codes,

Returns

y - cmat[:,NFFT] - carriers - QAM for data and BPSK for pilot carriers.
