This paper presents an analytical comparison of three modulation schemes applied to two low data rate (LDR) ultra wideband (UWB) non-coherent receivers, namely the quadratic detector and the differential detector. In order to evaluate properly the impact of UWB multipath channels on performance, new statistical models on energy collection are proposed, and(More)
In this paper, the ability of well-known energy detection (ED) and transmitted reference (TR) receivers for ultra wideband (UWB) low data rate (LDR) communications to detect synchronization sequences is studied. We focus especially on the degradation caused if, with an objective of low complexity, a hard decision is done on every chip of the sequence. The(More)
