Femtocells are envisioned as a key solution to embrace the ever-increasing high data rate and thus are extensively deployed. Given that numerous femtocell access points (FAPs) deployed in ultra- dense networks (UDNs) lead to significant energy consumption, boosting their energy efficiency (EE) becomes an important issue to be addressed. However, most existing works either focus on homogeneous networks...
Kalman Filter is an extremely effective and versatile procedure for combining noisy sensor outputs to estimate the state of a system with uncertain dynamics . In this paper, the algorithm of UFK(Unscented Kalman Filter ) is developed. By simulated experiment, EKF(Extended Kalman Filter ),UKF without and with GPS latency compensation are compared. In result,the UKF algorithm is unbiased and minimum...
In this paper, we consider a multi-antenna wireless multicast system with multiple multicast groups. The problem of resource allocation with downlink precoding for the multicast systems is studied, assuming the channel state information between transmit and all the receivers is available at the transmitter. Specifically, we formulate an optimization problem to maximize the system throughput given...
