IEEE 802.15.4a标准下基于半定规划算法的波形设计算法
Semi-Definite Programming Based Pulse Shaping Algorithm in IEEE 802.15.4a
为了增加Zigbee的峰值数据传输速率以及拓展其应用场景，IEEE 802.15.4a标准在2007年被提出，超宽带技术也被选作它的一个物理层标准。无线传感器网络的性能会受到信道中传输的脉冲波形的影响，因此，本文首先给出了中国的超宽带标准，然后遵循这个标准，提出了一种基于半定规划算法的波形设计算法。仿真结果显示，所提出的算法能满足给出的标准，并有较高的功率利用率，从而可以有效提高接收端的信噪比。
In order to increase the peak transmission data rate of Zigbee and expand its application scenario, IEEE 802.15.4a standard has been proposed in 2007, and ultra-wideband (UWB) technique has been selected as one of its physical layer standard. The performance of wireless sensor networks (WSN) will be affected by the pulse waveform transmitted in the channel, hence, in this paper, the Chinese regulation for UWB devices is firstly given, and then, a semi-definite programming based pulse shaping algorithm to comply with such regulation is proposed. Simulation results show that the proposed algorithm can comply with the given regulation with high power efficiency, which can increase the signal to noise ratio (SNR) in the receiver end.
