16 number consist two parts, called In-phase and 16 number consist two parts, called In-phase and Quadrature (IQ). Both I
17 and Q are represented as a 14 bit signed littl 17 and Q are represented as a 14 bit signed little endian number. I value
18 comes first and Q value after that. 14 bit val 18 comes first and Q value after that. 14 bit value is stored in 16 bit
