Next is the proposed method for optimizing the transmit power allocation. To maximize the system capacity of all OAM modes, the problem of optimizing the transmission power allocation of all OAM modes £ð can be formulated as Formula 2. This function is Loss function that minimizes interference from other OAM modes, which is a component that becomes noise when retrieving the received signal. There are two ways to solve this loss function. L1-ball projection approaches and L2-ball projection approach.
