Propomos o código de bloco espaço-tempo ortogonal de malha fechada baseado em símbolos combinados (CS-CL-OSTBC) para quatro antenas de transmissão. Nos sistemas de múltiplas antenas, o CS-CL-OSTBC não apenas atinge taxa total e diversidade total com detecção linear de máxima verossimilhança, mas também obtém maior ganho de feedback do que os CL-OSTBCs existentes devido à utilização mais eficiente das informações de feedback do canal. No esquema proposto, todos os coeficientes de canal de valor complexo são girados para valores reais positivos com informações exatas de feedback de fase do canal. Como resultado, o ganho do canal pode ser expresso como o quadrado da soma de todos os valores reais positivos e pode obter o valor máximo sem qualquer perda. Os resultados da simulação sobre o desempenho da taxa de erro de bits mostram que o CS-CL-OSTBC supera os CL-OSTBCs existentes para vários esquemas de modulação.

Abstract: We propose the Combined Symbol-based Closed-Loop Orthogonal Space-Time Block Code (CS-CL-OSTBC) for four transmit antennas. In the multiple antenna systems, the CS-CL-OSTBC not only achieves full rate and full diversity with linear maximum-likelihood detection but also obtains higher feedback gain than existing CL-OSTBCs due to more efficient utilization of channel feedback information. In the proposed scheme, all the complex-valued channel coefficients are rotated to positive real values with exact channel phase feedback information. As a result, the channel gain can be expressed as the square of the sum of all positive real values and can obtain the maximum value without any loss. Simulation results on bit error rate performance show that the CS-CL-OSTBC outperforms existing CL-OSTBCs for various modulation schemes.
