LS Channel Estimation for Mobile OFDM Communications on Time-Varying Frequency-Selective Fading Channels
Abstract— A least-squares (LS) channel estimation (CE) technique for mobile OFDM communications over a rapidly timevarying frequency-selective fading channel is investigated in t...

Error estimation in wireless sensor networks
We present an analogy between the operation of a Wireless Sensor Network and the sampling and reconstruction of a signal. We measure the impact of three factors on the quality of ...

Predetermination of ICP Registration Errors And Its Application to View Planning
We present an analytical method to estimate the absolute registration error bounds if two surfaces were to be aligned using the ICP (Iterative Closest Point) algorithm. The estima...
