Abstract :
The optimal rotations for quasiorthogonal space-time block codes (STBC) with MPSK symbols are presented, where the optimality means that the optimal diversity product is achieved. The optimal diversity products of quasiorthogonal STBC with rotated MPSK constellations are given. The sensitivity of the diversity product to the rotation angle offset is studied.
