Orbital angular momentum of vortex electromagnetic waves has the potential to overwhelmingly increase the system capacity for radio communications. To explore the performance of the novel multiplexing system, the influence of both detection schemes at the receiving side and power allocation methods at the transmitting side on channel capacity is investigated firstly by exploiting zero-forcing (ZF) and minimum mean square error (MMSE) detection schemes and water-filling algorithm. It is found finally that MMSE is superior to ZF generally, which conforms to the MIMO theory. And for rank-deficient channel, optimal power allocation will play a greater role to enhance system capacity.
