Effect of selecting antenna and template on BER performance in pulsed UWB wireless communication systems

The effects on BER performance of selecting antennas and templates are investigated in pulsed UWB wireless communication systems. The transmit and receive antennas are regarded as a system. The UWB system is characterized in the time and frequency domains, and the underlying relationships between BER, SNR, S-parameters and the template are revealed. The study has shown that when an antenna system has a high transmission efficiency and a template with high fidelity to the received pulse is chosen at the receiver, SNR increases so that BER decreases.
