Analysis of linear system response to wide band signals with applications to filters

The growing demand for broadband wireless communication links and the lack of wide frequency bands within the conventional spectrum causes us to seek bandwidth in the higher microwave and millimeter-wave spectrum at extremely high frequencies (EHF) above 30 GHz. One of the principal challenges in realizing modern wireless communication links in the EHF band are phenomena occurring during electromagnetic wave propagation through the atmosphere and in the linear systems of the receiver. A space-frequency approach for analyzing wireless communication channels operating in the EHF band is presented. The signal analysis is studied in the frequency domain, enabling consideration of ultra wide band modulated signals. The theory is employed for the analysis of a communication channel operating at EHF that utilizes pulse amplitude modulated signals.
