摘要

超宽带(UWB)技术被认为是实现认知无线电系统的一种合适的传输技术,在这种系统中,频谱敏捷的UWB波形可以实现自适应特性。设计这种波形的一种方法依赖于基于pswf的脉冲小波的正交组合。在有N个用户的认知UWB无线电环境中,针对一个用户接入一个子频带,发射信号为M-ary脉冲形状调制的情况,在多径衰落信道中发射这些脉冲得到不同的特征值,并根据不同的特征值提出了注水方案,以优化它们之间的功率分配。仿真结果表明,在超宽带通信中信噪比较低的情况下,与功率均等分配方案相比,该方案提高了子带信道的数据吞吐量

Transmit Power Allocation among PSWF-based Pulse Wavelets in Cognitive UWB Radio
Ultra wideband (UWB) technology has been considered as one of the suitable transmission techniques for implementing a cognitive radio system, where spectrum-agile UWB waveforms achieve adaptation features. One approach for designing such waveforms relies on orthogonally combining PSWF-based pulse wavelets. In a cognitive UWB radio environment with N users, with respect to the case of one sub-band accessed by one user, whose transmitting signal is M-ary pulse shape modulated, we get different eigenvalues by transmitting these pulses in a multipath fading channel, we propose water filling scheme, depending on the different eigenvalues, to optimize the power allocation among them. Simulation results show that the scheme improves the sub-band channel data throughput compared with the scheme that power is equal allocated among these pulse wavelets, when the SNR is low, which is the normal case in UWB communications
