Abstract :
Lower and upper bounds of feedback rate are presented for closed-loop pilot-aided multiple-input-multiple-output (MIMO) wireless systems. We validate the bounds of the wireless systems through simulations. The presented bounds and numerical results for various system configurations can be applied to evaluate the closed-loop MIMO wireless systems and are used as a benchmark for advanced systems
