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.

To solve the problems of high hardware complexity and sampling rate mismatch in the implemention of a transmit-filter module for E-band microwave transmission systems, a “zero multiplication” solution based on look-up table was proposed, and a hardware structure suitable for a transmit-filter's implementation using the mode of field-programmable gate array (FPGA) was designed. The theoretical hardware complexity analysis of the hardware structure, with its MATLAB simulation and FPGA assessments, were performed, and the results showed that the proposed structure completed the signal shaping filtering and resampling simultaneously with the low hardware complexity and high real-time performance. Compared with conventional convolutional based solutions, the proposed solution used only 16.7% of addition operation, with no mutiplexing operation being included. ©, 2014, Inst. of Scientific and Technical Information of China.
