英文摘要：

The performance of the spatially correlated MIMO- OFDM systems in the presence of phase noise and channel estimation error was analyzed to further understand effects of phase noise and channel estimation error on the spatially correlated muhiple-input multiple-output orthogonal frequency division multiplexing （MIMO-OFDM） systems. The complex envelope of the spatially correlated MIMO- OFDM signal was expressed in model. Symbol signal to noise model was derived and a performance degradation measure was defined and expressed for the spatially correlated MIMO - OFDM systems in the presence of phase noise and channel estimation error. The results of performance degradation of the spatially correlated MIMO - OFDM systems between the theoretical calculations and computer simulations match well in the presence of phase noise and channel estimation error.
