Transmit diversity in LTE network

This paper investigate the effect of transmit diversity in LTE downlink transmission. Transmit diversity scheme known as Space Frequency Block Codes (SFBC) is considered. As performances metrics, the average BER is evaluated in terms of signal to interference-plus-noise ratio (SINR). We evaluate the channel estimation scheme for LTE downlink based on 3GPP LTE downlink specifications in presence of high Doppler deviations. Finally the accuracy and effectiveness of the theoretical analysis is verified by the simulation with idealized multipath channel models as well as the ITU pedestrian and vehicular channel with high order modulation and coding scheme.
