Channel Design: A Novel Approach for Blocking Interference and Achieving Interference-Free Capacity

The topics of lifting the capacity and blocking the interferences of MIMO wireless systems are studied. The interferences can be blocked by filter design but with the consequence of noise enhancement and thus reduce the capacity. Or, the capacity can be maintained by filter design but some interference has to be accepted. In this paper, we present a new method, namely channel design, with which the interferences can be completely blocked and in the meantime the capacity is also lifted
