Objectives/Background: In Long Term Evaluation- Advance (LTE-A), there are different specialized elements accessible like odd time slots transmission, use of adaptive modulation etc. Notwithstanding, the BER performance analysis is required in genuine scattered environment like spatially correlated antennas at transmitter side and blemished channel state information accessible at the receiver (CSIR) for adaptive modulation. Method/Statistical Analysis:We are exhibiting Bit Error Rate (BER) performance of LTE-A full rate full diversity STBC under quasi-static fading channels with real practical assumption of spatially correlated antennas at transmitter side and blemished channel state information accessible at the receiver (CSIR). The spatial correlation between two antennas is supposed to be 0 1 < < η , where η is spatial correlation among two transmit antennas and imperfectness of channel state information available at receiver are supposed to be 0 1 < < ρ , where ρ the imperfection coefficient between actual channel and CSIR. Findings: It can be seen that at higher SNR channel state data accessible at receiver are more critical than transmit antenna correlation at transmitter.But at lower SNR up to 10dB, the impact of transmit antenna correlation at transmitter and channel state information at receiver is not assuming important part in the BER performance. Applications:This result analysis is useful for adaptive modulation in LTE-A full rate full diversity STBC where modulation orders have been change.
