On uplink CDMA cell capacity: mutual coupling and scattering effects on beamforming
It has been shown that code-division multiple-access (CDMA) systems that employ digital beamforming and base-station antenna arrays have the potential to significantly increase capacity. Therefore, accurate performance prediction of such systems is important. We propose to take the electromagnetic behavior of the base-station antenna array into account, as well as its impact on wireless channel...
متن کاملCapacity Enhancement of Ad Hoc Networks using a New Beamforming Scheme Based on ESPAR
This paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (ESPAR). The proposed method is capable of providing better capacity compared to the conventional ESPAR. The termination of each antenna element in this structure comprises a PIN diode in addition to a varactor. Using PIN diode besides the varactor provides more degrees of freed...

متن کاملBehavior of Model Circular Footings on Silty Soils with Cellular Supports
An experimental study of the effect of silt and influence of cell confinement on the bearing capacity of circular footings on silty sand was carried out. Laboratory experiments on clean sand and sand containing silt up to 25 % were performed. Cells with different heights and diameters were used to confine the silty sand. The effect of proportion of silt in sand, cell diameter, cell height and t...
متن کاملPerformance Evaluation of the NOMA in Imperfect SIC Mode and Ergodic Capacity Maximization with User Pairing Scenario in Three Users Groups
This paper evaluates the problem of user pairing scenario with similar channel conditions in NOMA with three users per pair. The small difference in the channel gain of the paired users leads to interference in the process of successive interference cancelation (SIC). The incidence of imperfect SIC reduces system capacity. Also, mid users in this scenario will be deprived of the advantages prov...
