Optimum IR-UWB Coding Under Power Spectral Constraints
نویسندگان
چکیده
Optimum coded Impulse-Radio Ultra-Wideband (IR-UWB) waveforms under power spectral constraints are investigated. Transmission over a SISO frequency-selective channel is assumed. An analytical solution for the optimum precoder is proposed, constraining compliance with a uniform mask in the frequency-domain and maximum transmitted power. Comparison against numerical solutions for non-uniform masks is also performed and a generalization of the analytical solution is proposed. Finally, practical design solutions and issues are presented.

Space-shape coded UWB-impulse radio system
Proposed is a novel space-shape coding scheme with multiple antennas and multiple orthonormal waveforms for UWB-IR systems. Since the proposed coding scheme can be applied for every frame, the spatial diversity can be achieved even without the invariant channel condition over frames. Furthermore, the proposed scheme can provide an additional power gain to enhance BER performance while the FCC s...

Ultra-wideband impulse radio (UWB-IR) sensors should comply entirely with the regulatory spectral limits for elegant coexistence. Under this premise, it is desirable for UWB pulses to improve frequency utilization to guarantee the transmission reliability. Meanwhile, orthogonal waveform division multiple-access (WDMA) is significant to mitigate mutual interferences in UWB sensor networks. Motiv...

Ultra Wide-Band (UWB) communication techniques have received increasing attention since United States Federal Communications Commission (FCC) adopted a “First Report and Order” [1] in 2002. Unfortunately the regulations that appeared a few years latter didn't have the same level of commitment and had much tighter constraints. The FCC part. 15 power spectral density limitation is depicted in Fig...

Trends in modern communication systems place high demands on low power consumption, high speed transmission and anti-interference characteristics. Therefore impulse radio ultra–wideband (IR-UWB) [1] radio systems have recently gained increased popularity. Since IR-UWB symbols are transmitted with short pulses (< 2 ns), in IR-UWB systems, energy has been spread over the frequency bands of up to ...

IEEE 802.15.4a impulse radio-time hopping ultra wide band (IR-TH UWB) physical layer, due to small duty cycle and very short pulse widths is robust against multipath propagation. However, scattering and reflections with the large number of obstacles in indoor channel environments, give rise to dense multipath fading. It imposes serious problem to optimum Rake receiver architectures, for which v...
