WebIn the proposed structure, we employ variable radio frequency attenuators at each phase shifter which flexibly controls the transmit signal amplitude to achieve the performance of fully digital (FD) precoders. We formulate a power loss minimization problem which can be easily solved via the alternating optimization process. la mijoteuseWeb1 ln 2 and the phase shift equals to q 2 = R 1 C 1 w ln 2 . It shows that the phase shift varies from R 1 C 1 w ln 2 to tan ( 1 1 ) −1 R Cw corresponding to the slew rate of the input. In the limiting process, the phase is disturbed by amplitude variation, or in other words, AM-to-PM conversion.
