Evolutionary design of seven-tier LM-mode filters optimized with original knowledge-based cad system

Abstract

The evolutionary strategy of multi-tier WDR-filters with LM-modes, optimized with original knowledge-based CAD system designing is proposed and tested. Main point of the strategy is to solve the problem of synthesis and optimization of the seven- (or more) tiered filter through the gradual complication of the simplest one-tiered design, which corresponds to the evolutionary principle of gradual cost function complication. The efficiency of the strategy is confirmed by the designing of three to five and seven-tier millimeter filters, which are intended for the next generation of millimeter wave-band wireless systems and conform to the latest standards like ECMA-387, Wireless HD, IEEE 802.15.3c and IEEE 802.11ad.
