For a downlink of Multiuser (MU) Multiple-Input, Multiple-Output (MIMO) system with 2 transmitting antennas at the base station and N receiving antennas at each user, in this paper, new decoding methods, named as affine projection decoders, will be proposed and illustrated based on the Almouti scheme, under assumptions that the transmitter does not have channel state information (CSI), and transmits...
For uplink of Multiuser (MU) Multiple-Input, Multiple-Output (MIMO) system with M receive antennas at base station and one transmit antenna at each user, in this paper, performances of linear decoders, namely Zero-Forcing decoder and Minimal Mean-Square Error (MMSE) decoder, are investigated. Differing from existing results which mainly describe various asymptotic properties, this paper gives analytical...
As a space- and cost-efficient antenna configuration, dual-polarized antennas are widely deployed in real field MIMO wireless communication systems. The Quasi-Orthogonal Space-Time Block Code (QOSTBC), due to its advantages in the transmission rate and the decoding complexity, is an important transmit diversity scheme for more than 2 transmit antennas. In this paper, we investigate the performance...
In order to fulfill the full flight envelope aero-engine control, as one of the most effective solutions, gain scheduling control system was designed in this paper which could weaken the influence of the limited robust of traditional controller. Based on the previous works such as the engine modeling and the two degrees-of-freedom (2DOF) H∞ loop-shaping controller design, the full flight envelope...
The design and verification of full flight envelope robust control system for aero-engine is presented in this paper. Firstly the full flight envelope was divided into eight regions and eight nominal points that represent each sub-region were selected based on the temperature and pressure of the engine inlet. Then based on the linearized engine model at each nominal point, two degrees-of-freedom (2DOF)...
Mobility Model has drawn more and more attentions since its important role in Mobile Ad hoc Network (MANET) protocol performance assessment. While MANET technology is widely used in Tactical Networks, research on Mobility Models oriented to Tactical Networks is still comparatively confined to the combination of traditional MANET ones. In this paper, a novel Tactical Unit Mobility Model Framework is...
