Planar complex unsigned 16-bit big endian IQ sample
|
|
|
|
Description
|
|
===========
|
|
|
|
This format contains a sequence of complex number samples. Each complex
|
|
number consist of two parts called In-phase and Quadrature (IQ). Both I
|
|
and Q are represented as a 16 bit unsigned big endian number stored in
|
|
32 bit space. The remaining unused bits within the 32 bit space will be
|
|
padded with 0. I value starts first and Q value starts at an offset
|
|
equalling half of the buffer size (i.e.) offset = buffersize/2. Out of
|
|
the 16 bits, bit 15:2 (14 bit) is data and bit 1:0 (2 bit) can be any
|
|
value.
|
|
|
|
**Byte Order.**
|
|
Each cell is one byte.
