Abstract
Methods and apparatuses for OAM precoder are disclosed. In one embodiment, an OAM transmitter comprises TX antennas; and a processor, wherein, the processor is configured to: transmit, via the TX antennas, at least two OAM modes including OAM mode (l, p) and OAM mode (−l, p), where l is a positive integer and p is a non-negative integer, each OAM mode transmits one layer of signal in each utilized polarization; and apply a precoding matrix to the transmission of at least (l, p) and (−l, p) to mitigate the cross interference between (l, p) and (−l, p).
