A Seven-Port Receiver for MIMO 2x2 Communication Systems

Abstract

In this paper, a single front-end seven-port receiver is proposed and analyzed for MIMO systems based on Alamouti coding. This architecture uses a single front-end which reduces the complexity in the RF section. The performances of our proposed seven-port receiver is assesed in term of two input QPSK modulated signals and bit error rates. The obtained results demonstrate that the proposed seven-port receiver can be a candidate for using in MIMO communication systems.
