This paper presents an architecture of an IR-UWB MB-OOK non-coherent transceiver. Channel measurements performed for both LOS and NLOS short-range communications in real indoor environment based on this realized prototype are provided. A comparison between the use of directional and omnidirectional antennas at both emission and reception is presented. Then, an estimation of the data rate of the communicating...
This paper presents an architecture of an IR-UWB MB-OOK non-coherent transceiver realized at Mitsubishi Electric. Channel measurements in real indoor environment based on this realized prototype are provided. The different components of this transceiver are described. A comparison between the use of directional and omnidirectional antennas at both emission and reception is presented. Then, a data...
This paper presents an implementation study of an analog pulse detector operating in the 3.1-10.6 GHz UWB band for a multi-band OOK receiver. The receiver's characteristics are in conformity with the specifications of UWB High Data Rates applications in terms of low cost and low power consumption. For that we especially focus on CMOS technology. This detector includes three stages: squarer, current...
Large peak to average power ratio (PAPR) is a common drawback of multicarrier signals. In wireless communication systems, dealing with high PAPR requires keeping an important margin from the power amplifier compression point. High power amplifier back-off leads to low power efficiency which is not suitable in many embedded systems. In this paper, a new iterative technique to reduce the PAPR of multicarrier...
