As we shall see, underdetermined systems always have an infinite number of solutions. Determined systems usually, but not always, have a single solution. Overdetermined systems are usually a problem and have to be carefully treated. Frequently, they

：提出一种基于独立成分分析（ICA）和位隙动态分组技术的超高频（UHF）射频识别（RFID）多标签防碰撞算法。利用ICA 算法实现多目标的同时识别，利用动态位隙标签分组保证阅读器同时读取的标签数少于或等 于其天线数，从而使ICA 工作于非欠定状态-A novel ultra high frequency (UHF) radio frequency identification（RFID）anti-collision algorithm based on independent compo
