A novel cell architecture based on Distributed Antenna Arrays for next generation mobile WiMAX systems is proposed. By exploiting Spatial Multiplexing and beamforming techniques, our target is to maximize the throughput of a high speed user by keeping low the deployment costs. Radio over Fiber is one of the best solutions to feed from a central point distributed arrays and share wireless resources...
It has been recognized that a primary method of further enhancing the spectral efficiency of LTE Release-8 is to improve support for multi-user (MU) MIMO transmission in the downlink in an efficient manner. This paper investigates the performance improvements due to the enhanced support of single-cell MU-MIMO within the framework of LTE evolution (specifically LTE Release-9 and Release-10 also known...
This paper presents a generalized expression for space-time cross correlation between signals at receiver antennas on a moving mobile in 3D space. This expression, which is a function of scattering environment coefficients, antenna locations and velocity of the mobile unit, will be useful for designers of communication systems in understanding space time correlation under various channel environments...
