Digital Architecture for an Ultra-Wideband Radio Receiver
نویسندگان
چکیده
This paper presents analysis of a digital Ultrawideband (UWB) radio receiver operating in the 3.1 GHz to 10.6 GHz band. Analog to digital converter (ADC) bit precision is analyzed on two types of UWB signals OFDM UWB and pulsed UWB all in the presence of Additive White Gaussian Noise (AWGN) and a narrowband interferer in the channel. This paper shows how probability of error and the bit resolution of the ADC can be scaled depending on the Signal to Noise Ratio (SNR), Signal to Interference Ratio (SIR), and the type of UWB signal. It also includes considerations on timing recovery for pulsed UWB.

متن کاملA/d Precision Requirements for an Ultra-wideband Radio Receiver
Ultra wideband radio (UWB) is a new wireless technology that uses narrow pulses to transmit information. Implementing an “all-digital” UWB receiver has numerous potential benefits ranging from low-cost and ease-of-design to flexibility. Digitizing an RF signal near the antenna, however, introduces its own set of challenges and has traditionally been considered infeasible. A high-speed, high-res...
