Detailed Description

template<class iType, class oType>
class GrWeaverModHead< iType, oType >

Head block of a Weaver SSB/VSB modulator.

Let the input rate be Fsym. Complex mix with cos/sin of Fsym/4 & interpolate by 2. This is typically used like this:

|---> matched filter --->| ---> GrWeaverModHead | | GrWeaverTail ---> |---> matched filter --->|

void GrWeaverModHead< iType, oType >::initialize  )  [inline, virtual]
 

Initialize any local state that is dependent on sampling frequency.

Reimplemented from VrSigProc.

template<class iType, class oType>
virtual const char* GrWeaverModHead< iType, oType >::name  )  [inline, virtual]
 

default name for a module (override with actual name)

Reimplemented from VrSigProc.

template<class iType, class oType>
int GrWeaverModHead< iType, oType >::work VrSampleRange  output,
void *  o[],
VrSampleRange  inputs[],
void *  i[]
[virtual]
 

Generate up to output.size output points at o[output#][sample#] using data at the inputptrs[input#][sample#].

Pointers start at corresponding VrSampleIndex in the range params. output.size is a multiple of outputSize. Returns the number of outputs (<= output.size) that it was able to compute with the given input ranges. If this value is < output.size, forecast() will need to be called again.

Reimplemented from VrInterpolatingSigProc< iType, oType >.
