int SIM::qam_dem::get_output

(

void

)

get output

Returns

- [int] y0

double SIM::qam_dem::get_scale

(

)

get scale

Returns

- scale factor

int SIM::qam_dem::get_size

(

void

)

get M - square constellation size 4,16,64,256,...

Returns

ivec SIM::qam_dem::process	(	const bvec &	ce,
		const cvec &	x
	)

for active clock ticks ce[i] return symbol code y[i] for a sliced complex input x[i]=I+j*Q

Parameters

ce	- bvec - clock_enable vector
x	- cvec - iq complex symbol - normalized [I,Q] = [(-1..+1),(-1..+1)]

Returns

y - ivec - symbol code vector

void SIM::qam_dem::set_output

(

int

yout

)

set output value y0

Parameters

[in]

yout

- [int] => y0

void SIM::qam_dem::set_scale
