Each complex 22number consist of two parts called In-phase and Quadrature (IQ). Both I 23and Q are represented as a 16 bit unsigned big endian number stored in 2432 bit space. The remaining unused bits within the 32 bit space will be 25padded with 0. I value starts first and Q value starts at an offset 26equalling half of the buffer size (i.e.) offset = buffersize/2. Out of 27the 16 bits, bit 15:2 (14 bit) is data and bit 1:0 (2 bit) can be any 28value. 29 30**Byte Order.** 31Each cell is one byte. 32 33.. flat-table:: 34 :header-rows: 1 35 :stub-columns: 0 36 37 * - Offset: 38 - Byte B0 39 - Byte B1 40 - Byte B2 41 - Byte B3 42 * - start + 0: 43 - I'\ :sub:`0[13:6]` 44 - I'\ :sub:`0[5:0]; B1[1:0]=pad` 45 - pad 46 - pad 47 * - start + 4: 48 - I'\ :sub:`1[13:6]` 49 - I'\ :sub:`1[5:0]; B1[1:0]=pad` 50 - pad 51 - pad 52 * - ... 53 * - start + offset: 54 - Q'\ :sub:`0[13:6]` 55 - Q'\ :sub:`0[5:0]; B1[1:0]=pad` 56 - pad 57 - pad 58 * - start + offset + 4: 59 - Q'\ :sub:`1[13:6]` 60 - Q'\ :sub:`1[5:0]; B1[1:0]=pad` 61 - pad 62 - pad 63
