چکیده
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.

Space-Time block codes from orthogonal designs
We introduce space–time block coding, a new paradigm for communication over Rayleigh fading channels using multiple transmit antennas. Data is encoded using a space–time block code and the encoded data is split into n streams which are simultaneously transmitted using n transmit antennas. The received signal at each receive antenna is a linear superposition of the n transmitted signals perturbe...
متن کاملOn Space-Time Block Codes from Complex Orthogonal Designs
Space-time block codes from orthogonal designs recently proposed by Alamouti, and TarokhJafarkhani-Calderbank have attracted considerable attention due to the fast maximum-likelihood (ML) decoding and the full diversity. There are two classes of space-time block codes from orthogonal designs. One class consists of those from real orthogonal designs for real signal constellations which have been...
متن کاملOrthogonal Space-Time Block Codes
in this paper, we provide a blind adaptive channel estimation method for decoding of orthogonal space-time block codes (OSTBC), which is built on the minimizing of an unconstrained cost function. The global minima of the cost function are analyzed. Both LMS and RLS algorithm realizations are given. Our method can adaptively track the time varying channel and decode transferred symbols without p...

In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...
