Abstract

In this paper, we propose space-time block codes based on constituent intersectant orthogonal designs. After channel model is formulated, we studied the space-time block codes from constituent intersectant orthogonal designs. At last we made simulations for the space-time block codes from complex orthogonal design and the space-time block codes from constituent intersectant orthogonal design to compare their performance. Compared with space-time block codes from complex orthogonal design when code rate is the same and transmission rate is fixed, space-time block codes from constituent intersectant orthogonal design with more transmit antennas can reduce bit error rate and symbol error rate, and these new codes have the same low decoding complexity as the space-time block codes from complex orthogonal designs.
