weird symbol mapping in OQPSK modulator
As I open the MATLAB’s OQPSK Modulator Baseband block (via Look Under Mask), there is a weird symbol mapping inside as this:
for binary symbol mapping: (0,1,2,3) –> (3,1,0,2)
for gray symbol mapping: (0,1,2,3) –> (3,1,2,0)
both are not any standard mappings nor differential! I wonder why?As I open the MATLAB’s OQPSK Modulator Baseband block (via Look Under Mask), there is a weird symbol mapping inside as this:
