N2 - Spatial modes, such as orbital angular momentum (OAM) modes, are of interest for creating high spectral-efficiency line-of-sight wireless links in propagation environments with limited diversity gain. Four-element receive arrays have been designed using a Monte-Carlo method so as to enable the simultaneous reception of four different OAM modes. A test-bed operating in the 5GHz band has been developed to validate the principle experimentally. The test bed's transmitter is an eightelement uniform circular array, which allows the generation of OAM modes with mode numbers l =ϵ(±3;±2;±1; 0). The receiver is a four element array, and all elements in the transmit and receive arrays have a dedicated programmable phase shifter to facilitate rapid adjustment between modes.
