An inter-vehicle communication system is highly advantageous for driving safety support systems, such as collision avoidance systems at intersections. In an inter-vehicle communication system, a channel-tracking scheme is essential to achieve reliable wireless communication under the fast fading environment caused by surrounding vehicles. For coherent detection, decision feedback is a well-known channel-tracking...
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...
This paper presents a VLSI implementation of a high throughput MIMO-OFDM system in wireless communications. We explore the optimum parameters in a new packet OFDM frame by expanding the IEEE802.11a standard. The proposed system provides a maximum of 600 Mbps by use of an 80-MHz baseband bandwidth and a 2 times 2 MIMO scheme. The proposed system is implemented into hardware according to a full-pipelined...
