This paper presents a new quadratic-time algorithm for joint Tx and Rx antenna selection (AS). The proposed approximate optimum executes much faster than the semidefinite-relaxation method, and hence becomes more robust in preserving full AS diversity for space-time coded systems over Rayleigh fading channels. Numerical results confirm the achieved approximation ratios of maximum mutual information and Frobenius norm of channel close to one.
