Ero-multiplication TX-filter structure for eband transmission system

In order to reduce the hardware complexity and unify the sampling rate of transmit filter (TX-filter) module, a novel lookup table (LUT) based zero-multiplication TX-filter structure is proposed for E-band microwave transmission system. Simulation results demonstrate that the proposed structure needs only 16.7% addition operation compared with conventional convolutional based solutions, no multiplexing operation included and an arbitrary sampling rate transform integrated simultaneously.
