  • Using a Compact Mapping Matrix (CMM) to transform a diagonal space-time coding, a design method for full-diversity space-frequency codes is proposed. Without losing the inherent space diversity of the space-time coding, the proposed space-frequency coding obtains extra frequency diversity provided by the frequency-selective fading channels and improve the performance. Further improvement is obtained by optimizing the coding gains. Exploring the diagonal structure of space-timing coding and the new research results, the proposed codes can be decoded with polynomial complexity. This facilitates the hardware implementation of the system.
