Description: Ajey, S., B. Srivalli, et al. (2010). On performance of MIMO-OFDM based LTE systems. Wireless Communication and Sensor Computing, 2010. ICWCSC 2010. International Conference on.
4G wireless systems predominately employ multiple input multiple output (MIMO) with an orthogonal frequency division multiplexing (OFDM) system. Like other 4G systems long term evolution (LTE) also employs MIMO-OFDM physical layer. MIMO helps in increasing the throughput whereas OFDM converts a frequency selective fading channel to multiple flat fading sub-channels facilitating easy equalization. It is proposed that LTE system should mandatorily support 2Ã — 2 MIMO setup. Our paper focuses on the performance of such a LTE system with two transmit antennas and two receive antennas in a frequency selective fading environment. Platform: |
