| Abstract: |
| A differential detection scheme is proposed which is based on Alamouti
′s transmission scheme, and the proposed scheme can provide higher spectrum eff
iciency with phase rotation. The simulation results show that the proposed schem
e increases the spectrum efficiency because of the angle information. On the oth
er hand, the idea of angle rotation in this scheme can potentially be used in ot
her differential detection scheme. |
