Channel map has been widely used as an effective tool in network planning and deployment. However, there is a lack of mathematical formulation of the channel map as a tool for multiple-input multiple-output (MIMO) networks planning. In this work, we define and construct a MIMO channel map based on the extension of a mathematical formulation for the conventional single antenna channel map. We demonstrate...
Path loss modelling and prediction is essential in indoor network planning. To find an efficient and accurate path loss model benefits the network planning and optimisation process. In this work, we propose an efficient multipath empirical path loss prediction model based on an intelligent ray launching algorithm for 60GHz indoor channel. The comparison between the simulation result and measurement...
This paper proposes an optimization model of multi-inventory matching and order planning of the iron-steel factories based on the mixed strategy of MTO-MTS. The model considers the multiple objectives, i.e., the total cost of earliness/tardiness penalty, tardiness penalty in delivery time window, production penalty; inventory matching, order cancellation penalty and machine capacity penalty. An improved...
In the context of heterogeneous networks, femtocells are very promising. In order to properly simulate their behavior and their impact on the macrocell layer, it is necessary to be able to simulate the radio coverage of femtocells. Hence ParFlow is a possible deterministic model that can be used for such simulation. In this paper two implementations of ParFlow are presented: time domain and frequency...
