WebThe conventional DWA algorithm is not direct to be used for the mismatch shaping of the SAR-type DACs that are widely used in NS-SAR ADCs. The emerging DWA algorithm requires an extra coarse ADC which complicates the system and thus limits the figure of merit of the high-resolution NS-SAR ADC. This paper presents vector pair based DWA … WebDWA combines the rolling window method for local path planning to avoid sudden unknown static and dynamic obstacles. In addition, this paper verifies the effectiveness of the algorithm through simulation. The simulation results show that the algorithm can avoid obstacles dynamically without being far away from the global optimal path.
