Abstract

This paper considers the implementation of two mobile user tracking systems that are based on different step-by-step adaptation schemes. We first estimate the computational complexities of different units of the tracking systems. Based on these estimations, we partition the implementation task into two parts: software and hardware. For the hardware implementation of the tracking unit a systolic architecture is proposed. With the aid of the proposed systolic array the time complexity of the tracking unit is reduced to O(M)
