I am using AD8347(0.8 GHz to 2.7 GHz Direct Conversion Quadrature Demodulator) to demodulate a BPSK modulated carrier wave. There is no intermediate frequency used.
By feeding the signal into this chip, I was able to get 4 outputs: IOPP, IOPN, QOPP, QOPN (I signal output positive, I signal output negative, Q signal output positive and Q signal output negative).
The source data is 115200 baud BPSK modulated to a 2.4GHz carrier wave. How do I analyze the 4 outputs to retrieve the original data? I understand that BPSK modulation meant that only the IOPP and IOPN signals are useful.
