Performance Analysis of Space Time Trellis Codes in Rayleigh Fading Channel

Main challenge in wireless communication field is to achieve reliable communication with flexible data rate providing services to large capacity under the restraint of limited power and limited available power and spectrum bandwidth. Space time trellis coding is also a space time code (STC) which provides both coding gain as well as diversity gain and has better bit error rate performance. In this paper, we discuss the performance of space time trellis code along with beamforming concept using various modulation techniques.
