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. 1. Introduction Multiple Input Multiple Output (MIMO) systems turns out to be extremely famous in wireless standards such as Wireless Local Area Networks (WLAN), Long Term Evolution (LTE), Digital Video Broadcasting (DVB), Long Term Evolution- advance (LTE-A) and Worldwide Interoperability for Microwave Access (WiMAX). We can accomplish high diversity gain or multiplexing gain uti- lizing MIMO systems. Performance of MIMO systems have been investigated and well documented in literature. Te transmission scheme, space time coding (STC) is widely known in MIMO systems. Te leading beneft of STC is less complexity, as the transmit diversity gain can be exploited without having CSI at the transmitter; for a case alamouti transmit diversity scheme 1–3 with two transmit antenna is orthogonal space time block code (OSTBC). It ofers diversity gain of two and code rate of one. Tough, schemes available for more than two transmit antenna can be composed which can give full diversity gain but not full code rate. It implies that the code rate is short of what one. In addition, alamouti STBC utilizes two or even time slots for transmission. In some wireless standards, for example LTE-Advanced, the choice is available in the frame structure to utilize three
