Abstract

This paper presents the implementation of space-time-frequency linear dispersion (LD) codes for multiple-input multiple-output (MIMO) antenna systems employing orthogonal-frequency-division-multiplexing (OFDM). The important properties of the LD codes are it can be used for any number of transmit and receive antennas and it is very simple to encode. Linear Dispersion Codes perform better than Alamouti codes. In this paper LD codes are implemented for 2X2 MIMO-OFDM system and the simulatation results show that the LD codes perform better than Alamouti codes.
