ABSTRACT
Despite the fact ultra-wideband technology has been around for over 30 years, there is a newfound excitement about its potential for communications. In this paper we are specifically focused on a software radio transceiver design for impulse-based UWB with the ability to transmit a raw data rate of 100 Mbps yet encompass the adaptability of a reconfigurable digital receiver. Direct sequence spread spectrum has become the modulation method of choice for wireless local area networks, because it's numerous advantages such as jammer suppression, code division multiple access and ease of implementation. We also observe its characteristics and complete the modulation techniques with MATLAB Simulink. The latter includes bit error rate testing for variety of modulation schemes and wireless channels using pilot-based matched filter estimation techniques. Ultimately, the transceiver design demonstrates the advantage and challenge of UWB technology while boasting high data rate communication capability and providing the flexibility of a research test bed.
