Abstract

The primary purpose of this paper is to present the space time block code for wireless networks that uses multiple numbers of antennas at both transmitter and receiver. LTE aims to provide enhanced service quality over 3G systems in terms of throughput, spectral efficiency, latency, peak data rate, and the MIMO techniques. Among several operational modes of MIMO, MU-MIMO, the base station transmits multiple streams to multiple users, has received much attention as a way of achieving improvement in performance. Space time wireless technology uses, multiple antennas along with appropriate signaling and receiver techniques offer a powerful tool for improving wireless performance. Space time block coding has been trying to incorporate in the fourth generation of mobile communications, which aims to deliver true multimedia capability. Simulation results have been shown that the STBC which includes the alamouti scheme as well as an orthogonal STBC for 4, 8 transmit antenna case has been simulated and studied. With orthogonal STBC, we have developed an 8 array antenna, which effectively handles large amount of data during transmission.
