“…Artificial intelligence (AI) [1][2][3][4][5][6][7][8] and robots [9][10][11][12][13][14][15][16][17][18][19][20] have given birth to a new wave of technological break throughs whereby the fusion of control systems with cognitive capabilities is not merely a dream but a reality that is not only being improved but also exploited with passion. The convergence is underlined by the Unscented Kalman Filter (UKF) [21][22][23][24][25][26][27][28][29][30][31][32][33], a sophisticated algorithm that has done a lot in advancing the abilities of AI-based robotics [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48].

This paper gives a bibliometric summary of Unscented Kalman Filter (UKF) in AI-infused robotics, highlighting its role in unifying control and cognition. Using a systematic approach that includes literature collection from IEEE Xplore, Web of Science and Google Scholar, rigorous screening and selection, and VOSviewer for a comprehensive bibliometric analysis. This analysis reports major trends, primary contributors and central themes, highlighting UKF's pivotal role in improving robotics cognitive and control capacities. The study emphasizes the universally used UKF in many fields of robotics, i.e. in navigation and mapping, sensor fusion, and state estimation, as one of its principal developers, which illustrates its vital role in promoting robotic autonomy and intelligence. The integration of findings from the bibliometric analysis thus not only presents the current state of research but also identifies possible future research directions, highlighting the increasing unification of control theories and cognitive processes in robotics. This research adds to the body of knowledge by delivering a comprehensive map of the UKF application. In this light, the UKF will be able to penetrate AI-infused robotics, the future of robotic developments will rely on the deep fusion of control and cognition facilitated by UKF and alike.

“…These techniques adjust the bias voltage or current in relation to output power level of the PA. For example, the dynamic bias techniques [1] control the gate or base bias of the power transistor in the PA to lower the constant bias current at low output power levels. The envelope-following techniques [2] directly modulate the DC voltage supply of the PA in such a way that the supply tracks the average output envelope. The supply voltage is decreased in a low output power region to save DC power consumption.…”

This paper presents design and linearization techniques for a highly efficient but nonlinear Class-E power amplifier (PA) applied to linear RF transmitters. A predistorted envelope modulation scheme is proposed to linearize the Class-E PA. To accomplish this scheme, the Class-E PA is designed with consideration of finite DC-feed inductance for wide supply-voltage modulation bandwidth. In addition, a digital envelope predistorter (DEP) is designed to provide the predistored envelope modulation for both RF-input and supplyvoltage signals fed to the Class-E PA. A cdma2000 1x transmitter incorporating such a Class-E PA and a DEP has been implemented to serve as an evidence for the simultaneous achievement of high efficiency and high linearity.Index Terms -Class-E power amplifier, linearization techniques, supply-voltage modulation, digital envelope predistorter.978-1-4244-1808-4/978-1-4244-1809-1/08/$25.00
