make_samples
Generation of I/Q samples from a binary stream (including upsampling and shaping filter).
Prototype
Veccf make_samples(const BitStream &bs, int ntaps, int osf, float &delay)
Parameters
| bs | Binary sequence. |
| ncoefs | Number of taps for shaping filter implementation. |
| osf | Oversampling factor. |
| delay | Delay, in number of output samples, between the beginning of the output I/Q stream, and the middle of the first symbol (the delay is due to the shaping filter). |
Description
This function will create, from a binary sequence, I/Q samples. The following steps are done:
- Constellation mapping,
- Upsampling,
- Shaping filter.
