| <para> |
| This format contains sequence of complex number samples. Each complex number |
| consist two parts, called In-phase and Quadrature (IQ). Both I and Q are |
| represented as a 14 bit signed little endian number. I value comes first |
| and Q value after that. 14 bit value is stored in 16 bit space with unused |
| high bits padded with 0. |
