Schemes of optimization of energy detection receivers for UWB-IR communication systems under different channel model

Optimization of energy detection receiver for UWB-IR systems with Inter-Symbol Interference cancellation

“…Next, determination of the optimal sample energy threshold is considered [5]. In proposed detection scheme, the threshold value is detected and the smaller energy sample than the threshold is ignored for detection to remove noise influence.…”

“…The ISI cancellation technique for energy detection had been proposed [2]. We have already considered the optimum integral interval and sample energy threshold value for energy detection receiver [3]. The better BER performances are obtained to be decided those values in IEEE802.15.4a channel environments.…”

A study on multi-user access in energy detection UWB-IR receiver

“…Although the energy e i (t) is integrated by the frame interval in the conventional energy detector, the integral interval and the sample energy threshold is estimated using pilot symbolẽ pilot (t) in optimized energy detector [4].…”

“…We had proposed the optimized the integral interval and the sample energy threshold in single user energy detection system [4]. And also the inter symbol interference mitigation technique is adopted [5].…”

Low Sampling Rate Time Acquisition Schemes and Channel Estimation Algorithms of Ultra-Wideband Signals

“…However, these approaches inevitably require a searching procedure and are inherently time-consuming. Too long synchronization time will affect (Carbonelli & Mengali, 2005;Furusawa et al, 2008;Cheng & Guan, 2008;Sasaki et al, 2010) is to synchronize UWB signals through the energy detector. The merits of using energy detectors are that the design of timing acquisition scheme could benefit from the statistical properties of the power delay profile of the received signals.…”
