According to the perspective of QPSK digital signal processing, design a block diagram for the given diagram below and explain for the given diagram (how does the signal go through the given diagram).

The following figure is a homodyne detection for coherent optical fiber communications . Once is the signal from laser and the other one is the local oscillator. After the QPSK demodulation, the electric field E will go through the photo diode detection. (you dont have to consider the photodiode in the block diagram design,but if you know how to do that, please do so :) )

The thumbs up will be guaranteed if you state your answer clearly :)
