Research on Design of Extending Orthogonal Space-Time Block Code
For the problem that complex orthogonal design of space-time coding cannot reach full speed and full diversity when the transmitting antenna number is greater than two, two kinds of improved schemes for the closed loop EOSTBC were proposed, which used the orthogonality of the equivalent channel matr...

| description | For the problem that complex orthogonal design of space-time coding cannot reach full speed and full diversity when the transmitting antenna number is greater than two, two kinds of improved schemes for the closed loop EOSTBC were proposed, which used the orthogonality of the equivalent channel matrix and the feedback of the channel information in the STBC system. The system was designed to maximize the equivalent channel gain. The first scheme was combined with antenna selection techniques and the second was combined with adaptive power allocation. Also, the feedback information was carried respectively. Then its performance was theoretically analyzed and compared. The simulation results show that the bit error rate of the system is reduced and the signal-to-noise ratio gain of the system is improved by the two kinds of improved scheme, and compared with the scheme which is combined with antenna selection technology, the performance of the second scheme combined with adaptive power allocation is superior. |
