Abstract : In this letter, we propose temporal modulation as a new dimension to enhance the performance of spatially modulated space-time block codes (STBCs). We efficiently integrate a cyclic spatially modulated codebook with temporal permutations over four consecutive time slots. To ensure a full transmit diversity order for the designed codebook, we assume that two distinct pairs from the available transmit antennas are activated over two consecutive time slots to construct a 2×2 STBC transmission matrix. We design a rotated version of the orthogonal full-diversity Alamouti STBC as a building block of our proposed codebook. Our numerical results confirm the reduced error rate of the proposed transmission scheme over the state-of-the-art schemes at the same spectral efficiency.
