Abstract :
In the multiple-input and multiple-output relay system, distributed spatial-temporal precoding (DSTP) has been proven to be capable of improving the system reliability and capacity with limited feedback. The outage performance of unitary DSTP is analyzed in this paper. By analyzing the singular values of the normalized equivalent channel, an upper bound of the outage probability is given. Then, the achievable diversity order is derived. Numerical and simulation results demonstrate the effectiveness of our analytical method.
