Abstract:
1. A pre-distortion method of correction of radio transmitter nonlinearity, comprising: representing the radio transmitter nonlinearity as a distortion function D(v), where v is an amplitude of a signal to be transmitted, and where a set of distortion components to be corrected are determined by an order of nonlinearity N to be corrected, where N is the order of non-linearity; receiving the signal to be transmitted Tx(f) having a maximum significant frequency component at frequency f using a pre-distorter having a transfer function D filtering the pre-distorted signal Tx passing the filtered pre-distorted signal Tx where the EBEE filter has a filter characteristic of H up-converting the signal Tx transmitting the up-converted signal Tx
