Description
Summary:This paper compares the uniform circular array based or bital angular momentum (UCA-OAM) scheme, which enables spa tial multiplexing transmission of data symbols via multiple OAMmodes, with the UCA-MIMO scheme through numerical analysisand simulation in terms of spectral efficiency and feedback over head. Specifically, based on the relations between the eigenmodesof the UCA-SVD-MIMO system and the modes of UCA-OAM sys tem as well as the capacity formula, the channel capacities of thetwo systems are compared for the cases where equal power alloca tion and waterfilling power allocation are employed, and then theeffectiveness of the analytical results are verified through simula tion.
