One of the fundamental research areas in wireless communications is the development of realistic models that can efficiently and accurately describe the wireless propagation channel. In this paper, the authors developed an asymmetric geometrical-based statistical channel model for mobile system and investigated the multiple-input and multiple-output (MIMO) receiving performance. This work was first...
In this paper, the effects of antenna element mutual coupling on MIMO system in a three dimensional multipath channel, are derived. Mutual coupling between elements of ULA, UCA and URA, which influences both the spatial correlation and received signal to ratio(SNR), is taken into account by means of the impedance matrix. The general spatial correlation expressions of channel model with the impact...
Multiple input multiple output (MIMO) communication architecture has spectral efficiencies far beyond those offered by conventional techniques, and is greatly to increase the channel capacity. In this paper, we investigate the MIMO channel capacity in correlated channels using the uniform angular distribution, numerical simulations are performed with Matlab to verify the proposed formula. We prove...
Multiple antenna systems are promising architectures for overcoming the effects of multi-path interference and increasing the spectrum efficiency. Capacity increases promised by MIMO systems mostly depend on the spatial correlation properties of the radio channels. This letter investigates the performance of multiple-input and multiple-output (MIMO) antenna arrays systems including MIMO space-time...
Spatial correlation is one of the impairments practical multiple-input multiple-output (MIMO) wireless communication systems have to be coped with. Capacity increases promised by MIMO systems mostly depend on the spatial correlation properties of the radio channels. This paper investigates the connection between these properties and the channel capacity. By investigating the channel capacity using...
In this letter, we investigate the impact of fading correlation on symbol error rate (SER) performance of M-ray phase shift keying (MPSK) with maximal ratio combining (MRC) and present a comparison between the SER performance of a uniform circular array (UCA) and a uniform linear array (ULA). The performance evaluation uses the known expression for the SER of MPSK, then averages it over the density...
