On the Influence of Pulsed Jamming and Coloured Noise in Uwb Transmission

چکیده
This paper compares the performances of an ultra wideband (UWB) system in additive white Gaussian noise (AWGN) channel in presence of a pulsed jamming or a coloured Gaussian noise allocated in the UMTS-FDD (FDD = Frequency Division Duplex) uplink band. Several modulation schemes have been implemented in order to analyze the efficiency and the robustness of different UWB systems when the studied interferences are present in the channel. Results showed that the particular UWB modulation scheme chosen doesn’t affect effectively the degradation of performances introduced by the interference, giving a precise rank order for the different UWB concepts. Nevertheless, due to the band allocation of the interference, the pulsed jamming source worsens the performance of the system more significantly than the coloured noise for low interference power. For high values, instead, the behaviour is inverted.

This paper evaluates the level of interference caused by different ultra-wideband (UWB) signals to other various radio systems, as well as the performance degradation of UWB systems in the presence of narrowband interference and pulsed jamming. The in-band interference caused by a selection of UWB signals is calculated at GSM900, UMTS/wideband code-division multiple-access (WCDMA), and global p...
متن کاملPerformance Study of Untrusted Relay Network Utilizing Cooperative Jammer
Abstract—In this paper, the problem of secure transmission in two-hop amplify-and-forward (AF) systems with an untrusted relay is investigated. To prevent the untrusted relay from intercepting the source message and to achieve positive secrecy rate, the destination-based cooperative jamming (DBCJ) technique is used. In this method the destination sends an intended jamming signal to the relay. T...
متن کاملAnalysis of UWB Interference to MPSK Narrowband Receivers
This paper studies the in-band interference of time-hopping spread spectrum (TH-SS) ultra-wideband (UWB) signals to narrowband receivers. Based on the analysis of general power spectral density (PSD) of TH-SS UWB signal, the interference of UWB signal is partitioned into two parts: (1) additive white Gaussian noise interference, and (2) jamming tone interference. Following this framework, a nov...
