Codeword matching and signal aggregation (CMSA) is a recently proposed low-complexity noncoherent receiver for block-code-modulated ultrawideband impulse radio (UWB-IR) systems. As the frame/symbol duration is shortened to boost data rate, interframe interference (IFI) or intersymbol interference (ISI) occurs and degrades the detection performance of CMSA. In this paper, an effective IFI/ISI premitigation...
Recently, vehicular sensor networks (VSNs) have emerged as a new wireless sensor network paradigm that is envisioned to revolutionize driving experiences and traffic control systems. Many existing routing protocols for VSNs have good performance on data routing in a city environment. In this paper, we propose a traffic control aware routing for VSNs, which is called PUT. It considers two modules of...
Existing inter-frame interference (IFI) and intersymbol interference (ISI) mitigation schemes for noncoherent UWB Impulse Radio (UWB-IR) mainly focus on signal processing after nonlinear autocorrelation receiver (AcR) or energy detector (ED). Steering the wheel, a simple but effective IFI and ISI pre-mitigation scheme is proposed in this paper, which realizes IFI and ISI mitigation before ED. Block...
In order to improve the transmission performance in inter-symbol interference channel, a controlled inter-symbol overlapping transmission scheme to obtain high frequency efficiency, which is called inter-symbol overlapping transmission (ISOT), is studied. ISOT allows K symbols to be simultaneously transmitted without increasing channel bandwidth, and the symbol transmission interval can be decreased...
