Abstract :
This paper studies the BER performance of a multiband UWB system with a common RF and ADC module in the receiver. Communication signals in multiple RF bands are received by one UWB antenna. The ADC samples the received signal in a swath. This means that the RF signals with lower frequencies are oversampled. Using the ADC output signal, the demodulator demodulates each RF signal individually. The quantization noise process depends on the resolution of the ADC and is considered as a uniform distribution. The bit error rate of each RF signal is analyzed. Numerical results are provided for different ADC resolution. The results can help system designer to choose the right resolution for ADC in multiband UWB communications systems.
