- W2377319484 abstract "Implementation complexity and power consumption are significant issues in ultra-wide band(UWB) system design.An UWB system that employs discrete Hartley transform(DHT) to perform modulation and demodulation is proposed.The algorithms for channel estimation and equalization are derived.Compared with the scheme based on conventional OFDM,the proposed scheme requires much lower algorithm complexity,hardware complexity and power consumption,meanwhile,provides inherent frequency diversity.Convolution coding,frequency domain spreading and interleaving are employed to combat frequency selective fading and inter-symbol interference.The system parameters are designed according to typical UWB channels and simulations have been done to verify the system performance." @default.
