Transmit Beamforming for Performance Enhancement of IEEE 802.16e Mobile WiMAX
In this paper, the authors aim at performance evaluation of mobile WiMAX system which uses multiple antenna technique such as space time block coding space time trellis coding with and without transmit beamforming for multiple transmit and multiple receive antennas. The mobile WiMAX system has been analyzed for modulation scheme such as mPSK along with different combination of multiple transmit and receive antenna. Computer simulations are done using Matlab 7.10. The performance of the proposed system has been analyzed in terms of Bit Error Rate (BER).
