Circular Antenna Array to Suppress the Cochannel Interference in MIMO-OFDM Wireless Communication Systems

摘要：

This paper proposes the circular antenna array to suppress the cochannel interference for multipleinput multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) modulation systems. The conventional cochannel interference suppression system employs the linear antenna array in the receiver side, and the capability of circular antenna array in suppressing cochannel interference is not investigated so far. This paper proposes the circular antenna array to the conventional cochannel interference suppression system, and derives a theoretical measurement for evaluating the cochannel interference suppression capability. Computer simulations under IEEE 802.11a demonstrate the validity of the proposed circular antenna array.
