Abstract :
A novel scheme for ultra wideband (UWB) transceiver based on decision feedback using average differential transmitted reference (ADTR) is proposed in this paper. The system that averages multiple previous data pulses to form a cleaner template can reduce the noise level, but it does not need to transmit any reference signals before data-modulated waveforms. Furthermore, a combination of direct sequence spread spectrum (DSSS) and impulse radio (IR) based UWB transmitter architecture is developed. The DSSS is used only for multiple access. At the transmitter, a 0.5 ns wide UWB pulse is generated via a step recovery diode (SRD) and Binary Phase Shift Keying (BPSK) is implemented using Field Programmable Gate Array (FPGA). Other modulations could be easily designed by using software. Simulation results show that ADTR-DSSS-IR-UWB scheme could greatly reduce the transceiver complexity and is suitable for a variety of ultra-wideband communication systems.
