Performance of full-rate and partial-diversity multiple antennas space-time block code with low complexity
On the basis of existing full-diversity space-time block coding （STBC）, two full-rate complex orthogonal STBC schemes for multiple antennas were proposed. One was based on time division duplex （TDD） mode; the other had general application without being limited in TDD mode. Meanwhile, Turbo coding wa...

| Summary: | On the basis of existing full-diversity space-time block coding （STBC）, two full-rate complex orthogonal STBC schemes for multiple antennas were proposed. One was based on time division duplex （TDD） mode; the other had general application without being limited in TDD mode. Meanwhile, Turbo coding was adopted to improve the performance of proposed schemes further by utilizing its good ability to combat the burst error of fading channel. Compared with full-diversity multiple antennas STBC schemes, the proposed schemes could implement full rate, lower complexity and partial diversity; and had more spatial redundant information. Thus the concatenation of Turbo coding could effectively compensate for the performance loss due to partial diversity. Simulation results show that on the condition of same system throughput and concatenation of Turbo code, the proposed code schemes have lower bit error rate （BER） than those low-rate and full-diversity codes. |
