In this paper, under the IEEE 802.15.4a line-of-sight (LOS) and non-line-of-sight (NLOS) industrial multipath environments, the performances of the selective RAKE receiver and the differential detection receiver are simulated for impulse radio ultra-wideband (UWB) systems. The simulation results reveal that in the LOS industrial environments the selective RAKE receiver has better performance. In the...
In this paper, the performances of the selective Rake receiver and the transmitted reference (TR) receiver are evaluated through computer simulations, for impulse radio ultra-wideband (UWB) systems. The performances of these two receivers are compared by bit error rate (BER), system complexity, and implementation considerations, under IEEE802.15.4a industrial line-of-sight (LOS) and non-line-of-sight...
In this study, a new method for digitizing a combination of different analog signals occupying significantly different bandwidths and having a very high dynamic range is proposed and analyzed. Since it is based upon signal-prediction/cancellation principles, it is referred to as adaptive prediction and cancellation digitization (APCD) method and is applied to various families of signals simultaneously...
