Reduced-Complexity Receiver for Free-Space Optical Communication over Orbital Angular Momentum Partial-Pattern Modes

Figure 5

(a) Two transmitters (Tx1, Tx2) with overlapping beams at the receivers (Rx1, Rx2). (b) Schematic for two overlapping beams where we exclude the largest interfering quarter of the matching pattern to maximize the achieved rate. Rx1 will be only the green area, and receiver 2 will be the yellow area.
