modem.oqpsk with half sine wave

Question

hi i was using the following

             h = modem.oqpskmod; 

but it constructs it with default settings, i wanted to model zigbee one which is oqpsk with half sine waves... how could i do it? thanks a lot!

Answer 1

I think you can try this

 h = modem.oqpskmod('M',4,'SymbolOrder','Gray','InputType','Bit');
 Data = randint(10000,1);
 output = modulate(h,Data);
 plot(output, 'DisplayName', 'output', 'YDataSource', 'output'); figure(gcf)

You can see that the output is and compare it with the graph in there.
