Design and Implementation of Real-Time Localization Algorithms Based on FPGA for Positioning and Tracking

Due to the rapid development of wireless communication applications, software implementations cannot fulfill real-time computing to satisfy the in-time requirement of location-based services (LBS) applications. This article presents a location-estimation technique based on positioning and tracking algorithms, and the high-performance algorithms are implemented in field programmable gate array (FPGA) approaches, which have the features of pipeline structure and real-time processing. In terms of the FPGA approaches, our results demonstrate that the performance of location accuracy of the proposed approaches is almost the same as those of the software implementations, and it has the advantage of processing time.
