This paper reports on an innovative cooperative wireless localization network layout and the design of its network nodes. Each node consists of a 24 GHz FMCW secondary radar for bilateral range measurements between all nodes. Network synchronization and scheduling is based on IEEE 802.15.4 radio units. A novel concept to distributedly pre-synchronize all network nodes with an error of less than 125...
This paper discusses the performance of the wavelet based filtered multi-tone (WFMT) modulation. The novel WFMT modulation was proposed in 2003 for improving characteristics of wireless and DSL multicarrier systems. In this paper we describe a main idea of WFMT and discuss the advantages of this novel modulation. The WFMT modulation in comparison with OFDM and DMT has low level of out-of-band side...
