Addition of signals in simulink
2 views (last 30 days)
I have two signals I would like to add together using simulink (Inphase and Quadrature). These would have to be added using a signal from t = 0- 1 from inphase, then t = 0-1 quadrature, then t = 1-2 inphase, t = 1-2 quadrature etc..
How would i do this without using the QPSK demodulator block? I already have the inphase and quadrature signals in two differrent 'streams'

To demodulate the I and Q signals without using QPSK demodulator block can be done for the hard decision. You can get I and Q signals in two different streams and give it to the hard decision using the following block by setting a constant value to 'zero'
You will get bit outputs.
For combining real I and real Q to complex data, you can use
