WebThis example shows how to use the DC Blocker to remove a DC offset from fixed point data. Load the DC Blocker example by typing ex_dcblock_cicmode in the MATLAB command prompt. In the model: 64-QAM data passes through an AWGN channel. A DC offset of 1 is added to the signal . The Double -> Fixed block converts the data to 16-bit … WebAnd this was causing my signal to be shifted down within the detector. Now, placing an RF choke before the diode, it offers a DC return, and the RF signal has no offset. Then after the diode+RC I'm getting the envelope + DC RSSI which I block using the output cap and get only the envelope on the following stage. Then, yes, it's working now.
