* \brief Modulate a vector of data and apply a shaping filter.
*
* \p modulator: Pointer to a byte-to-complex modulator block.
* \p data: Vector of bytes to modulate into symbols.
* \p taps: Post-modulation symbol shaping filter taps.
*
* \details
* This function modulates the input vector and applies a
* symbol shaping filter. It is intended for use with the
* corr_est_cc block as the symbol stream to correlate
* against.
*
* Any differential encoding or other data coding must be
* performed on the input vector before this modulation
* operation.
*
* Be aware that the format of the incoming data must match
* the format the modulator block is expecting. GNURadio
* modulator blocks are inconsistent in their data type
* expectations. For instance, cpmmod_bc expects unpacked,
* signed bytes in (-1, 1), while gmsk_mod expects packed,
* unsigned bytes in (0, 1). In other words, the output of
* gmsk_mod given the input vector [0xaa, 0x00] is equivalent
* to the output of cpmmod_bc given the input vector
* [1,255,1,255,1,255,1,255,255,255,255,255,255,255,255,255]
*
* Please check the documentation or source of the modulator
* before using this function.
