STBC is a technique to achieve transmit diversity.
QO-STBC is full rate STBC constructed from relaxing orthogonality, and requires a decoder to search symbol pairs with ML decoding.
Motivated by this, we have proposed single symbol decodable QO-STBC with full diversity.
This code achieves full transmit rate and low system complexity.
However, the proposed QO-STBC can achieve a throughput performance like SISO.
In order to exploit the advantages of single symbol decodable QO-STBC, the combination of the proposed QO-STBC and an adaptive modulation has been considered.
To enhance the system performances of AMC QO-STBC, we introduce asymmetric constellation as one of modulation methods.
The system performances of non-adaptive QO-STBC and single symbol decodable AMC QO-STBC are evaluated and compared.
It is shown that the proposed scheme can greatly improve the performance of non-adaptive QO-STBC system. |
