Member Function Documentation

cvec SIM::cofdm_dem::get_carriers

(

)

get carriers - by setting new demodulator output - complex carriers CC = [I+jQ]

Returns

- [cvec] complex carriers CC = [I+jQ]

int SIM::cofdm_dem::get_CP

(

)

get CP size

Returns

- [int] CP size

int SIM::cofdm_dem::get_NFFT

(

)

get FFT size

Returns

- [int] FFT size

double SIM::cofdm_dem::get_scale

(

)

get scaling factor

Returns

- [double] scaling factor

cvec SIM::cofdm_dem::get_symbol

(

)

get symbol - demodulator input - complex time domain samples x = [CP|INV_FFT(CC)]]

Returns

[cvec] complex time domain samples

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

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

Parameters

ce	- bvec[:] - clock_enable vector,
x	- cmat[:,NFFT+CP] - cofdm symbols matrix,

Returns

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

void SIM::cofdm_dem::set_CP

(

int

cp

)

set size of CP - Circular Prefix

Parameters

[in]

cp

- CP size

void SIM::cofdm_dem::set_NFFT

(

int

n

)

set FFT size (N=2^k)

Parameters

[in]

n

- FFT size

void SIM::cofdm_dem::set_scale

(

double

s

)

set scale - default scaling is set by set_NFFT() and set_CP()

Parameters

[in]

s

- scale

void SIM::cofdm_dem::set_symbol

(

cvec

x

)

set symbol - demodulator input - complex time domain samples x = [CP|INV_FFT(CC)]]

Parameters

[in]

x

- complex time domain samples
