float GrAtscBitTimingLoop2::filter_error ( float e ) [inline, protected]

int GrAtscBitTimingLoop2::forecast ( VrSampleRange output,

VrSampleRange inputs[]

) [virtual]

map output range to required input ranges

Reimplemented from VrDecimatingSigProc< float, float >.

virtual const char* GrAtscBitTimingLoop2::name ( ) [inline, virtual]

default name for a module (override with actual name)

Reimplemented from VrSigProc.

GrAtscBitTimingLoop2::iType GrAtscBitTimingLoop2::produce_sample ( const iType * in,

unsigned int & index

) [protected]

Produce samples equally spaced in time that are referenced to the transmitter's sample clock, not ours.
See pp 523-527 of "Digital Communication Receivers", Meyr, Moeneclaey and Fechtel, Wiley, 1998.

void GrAtscBitTimingLoop2::set_mu ( float a_mu ) [inline]

int GrAtscBitTimingLoop2::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.
Implements VrSigProc.
