Many accidents occur today when distant objects or roadway impediments are not quickly detected. To avoid these accidents, longer-range safety systems are needed with real time detection capability. To avoid road traffic collisions, vehicles required to be broadcast their position and speed to nearby vehicles periodically. In the above said method, to implement vehicle safety systems with one or two...
This paper presents a fully integrated single-chip UHF radio frequency identification (RFID) reader transceiver for short distance handheld applications. The transceiver integrates an OOK modulator and a power amplifier in transmitter chain, an IQ direct-down converter, two operational amplifiers, and two comparators in the receiver chain. A PLL frequency synthesizer is also integrated on the same...
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...
