| Popis: | In this study, we estimated the performance of an orbital angular momentum (OAM) mode multiplexing transmission using a uniform circular array when the antenna swung. To compensate for the inter-mode interference caused by antenna swinging, OAM mode de-multiplexing was adaptively controlled by a least mean squares algorithm. Experimental results showed that stable transmission was achieved by the optimum loop bandwidth of the feedback loop in the E-band. |
