I/Q Data Binary File
The I/Q data is saved in binary format according to the format and data type specified
in the XML file (see Format element and DataType element). To allow reading and
writing of streamed I/Q data all data is interleaved, i.e. complex values are interleaved
pairs of I and Q values and multi-channel signals contain interleaved (complex) sam-
ples for channel 1, channel 2, channel 3 etc.
Example: NumberOfChannels - Element ordering for complex cartesian data
Complex data: I[channel no][time index], Q[channel no][time index]
I[0][0], Q[0][0], // Channel 0, Complex sample 0
I[1][0], Q[1][0], // Channel 1, Complex sample 0
I[2][0], Q[2][0], // Channel 2, Complex sample 0
I[0][1], Q[0][1], // Channel 0, Complex sample 1
I[1][1], Q[1][1], // Channel 1, Complex sample 1
I[2][1], Q[2][1], // Channel 2, Complex sample 1
I[0][2], Q[0][2], // Channel 0, Complex sample 2
I[1][2], Q[1][2], // Channel 1, Complex sample 2
I[2][2], Q[2][2], // Channel 2, Complex sample 2
