Novel LTE-A High Rate and Full Diversity Space Time Block Code for Two Transmit Antenna and Three Time Slot

Abstract

In long term evaluation- advanced (LTE-A), there is odd time slot available for data transmission in space time block code wireless communication system. But, higher code rate space time block code offer better data rate in long term evaluation- advanced (LTE-A) where odd number of time slot is available for transmission. In this paper, two new higher code rate space time block code have been proposed for two transmit antenna and one receive antenna using three time slot. Proposed space time block code BER performance outperform over alamouti space time block code. It also outperform in terms of code rate as well. Simulation results show that all proposed schemes give better performance in higher signal to noise ratio for given modulation order. This schemes offer higher code rate i.e.1.33 than alamouti full rate (code rate-1) scheme. At lower signal to noise ratio, the BER performance of proposed- 1 space time block code scheme offers better response than proposed- 2 space time block code scheme. At higher signal
to noise ratio, proposed-1 and proposed-2 space time block code schemes have better alamouti BER performance.
