WEIGHTED SPACE TIME TRELLIS CODE FOR STUDENT–T DISTRIBUTION CHANNEL

Mandeep Kaur

Abstract :

In this paper we present the concept of weighted space–time trellis codes. These codes are a grouping of space–time codes and ideal beam forming. It has been revealed that if perfect CSI is available at transmitter, the performance of STTC can be further enhanced through weighting the transmitted signals. In this thesis, we weight up the performance of STTC combined with ideal beam forming over slow fading channels. In this paper we present the theory of weighted space–time trellis codes. These codes are a combination of space–time codes and ideal beam forming. In this paper, we weight up the performance of space–time trellis codes combined with ideal beam forming over slow fading channels using 4–QAM and 4–PSK modulation schemes in which we have used two transmit and four receive antennas. Simulation results demonstrate that the projected scheme extensively outperforms the predictable space–time trellis without weighting
