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

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

Parameters

ce	- bvec - clock_enable vector
x	- ivec - symbol code vector

Returns

y - cvec - iq complex symbol normalized iq = [-1..+1][-1..+1] ;
