“…To evaluate this technique, we have calculated the average gain in the maximum data rate for a different number of reflected pulses and different delay distributions in the multipath components. This gain is defined as the increase of the data rate using the pulse interspersing technique with respect to the traditional IR approach [15]. Figure 5 shows this average gain, calculated by averaging the T S obtained with algorithm 1, considering between 1 and 10 reflected pulses randomly distributed between T b and certain maximum time delay between T b and 30T b .…”

“…We assume that the rest of multipath components will be negligible. The maximum data rate achieved in traditional incoherent IR-OOK schemes depends on the position of the last multipath received [15], and determines the inter-symbolic time T S . Consequently, the later the last reflected pulse arrives, the lower is the data rate.…”

Communications are becoming the bottleneck in the performance of Chip Multiprocessor (CMP). To address this issue, the use of wireless communications within a chip has been proposed, since they offer a low latency among nodes and high reconfigurability. The chip scenario has the particularity that is static, and the multipath can be known a priori. Within this context, we propose in this paper a simple yet very efficient modulation technique, based on Impulse Radio -On-Off-Keying (IR-OOK), which significantly optimizes the performance in Wireless Network-on-Chip (WNoC) as well as off-chip scenarios. This technique is based on interspersing information pulses among the reflected pulses in order to reduce the time between pulses, thus increasing the data rate. We prove that the final data rate can be considerably increased without increasing the hardware complexity of the transceiver.

“…Typically, in PUD-based systems, the pulses , are nonoverlapping in frequency. An example of nonoverlapping FDM with OOK is given for UWB systems in (Paquelet, 2004). Overlapping FDM signals were analyzed in (Al-Dweik, 2003) using the PUD approach.…”

In this paper, joint estimation of the optimal threshold, synchronization point, and integration interval is developed for ultrawideband (UWB) energy detectors employing on-off keying (OOK) modulation. Gaussian approximation of the received signal statistics is shown to enable low complexity solutions at the expense of some performance degradation. The performances of the optimal and suboptimal solutions are evaluated and compared. It is shown that explicit BER minimization is required for parameter optimization. Using simulations, number of training symbols required to converge to ideal parameter estimates is demonstrated to be increasing with increasing SNR.
