Planning and Realisation of Soil Remediationon (CSI), which are difficult to obtain in practice when channel coherence time is short and the number of mobile users is huge. Therefore, a critical question is how to make the system perform well with imperfect CSI. Rateless codes with adaptive code-rates can free the system from the accurate CSI

Monitoring and Monitoring Plans network topology in ad hoc networks. To this end, we focus on how to construct the network topology, which has the minimum network cost subject to a connectivity constraint. A new topology metric for each link, called connectivity-cost-ratio, is defined as the ratio of the connectivity contribution

Monitoring and Monitoring Plansror rate (BER). In this paper, the waveform design schemes, which are sine amplitude modulation (AM-sine), dual-frequency amplitude modulation (DFAM) and constant modulus dual-frequency (CMDF) modulation for wireless communication networks employing UNB technique, are proposed. We investigate the Eu

However, there still exist many challenges to ensure the D2D communication and the 5G standard hasn’t been released. In order to promote the development of D2D technology and provide a simulat

Planning and Realisation of Soil Remediational frequency division multiplexing (MIMO-OFDM) system. Using the hierarchical structure of the MIMO-OFDM systems, channel estimation and signal detection are alternately performed iteratively. Firstly, to reduce the complexity of channel estimation algorithm, an improved minimum mean squared error (

Therefore, it cannot fully meet the U.S. Federal Communication Commission (FCC) on radiation template requirements. Meanwhile, in order to avoid the interference with other wireless systems
