Abstract
Low complexity mobile speed estimation is required for power control, mobility and resource management, effective handoff, and outage probability computation of cellular mobile communication systems. It is also useful for mobility determination and energy-efficient packet routing in wireless sensor and mobile ad-hoc networks. In this paper, we present a low complexity mobile speed estimation model using count of peaks and troughs of the received signal envelop. Our simulation result shows that the model has a maximum error of 0.25 m/s. The model has two advantages. First, it does not require measurement of the received signal power; it only counts envelop peaks and troughs. Second, the model is independent of dc offset inherent in the radio receivers. However, the model has one limitation- it does not give the crossing component of a mobile’s velocity.
