Abstract :
Current digital implementations of the LINC transmitter´s signal component separator use large two-dimensional lookup tables. The effects and benefits of using a smaller one-dimensional lookup table are discussed, and simulation results are given showing that the size of the lookup table can be reduced by several orders of magnitude without affecting the transmitter´s linearity
