+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.
