The CP-free MIMO-OFDM system is considered to be an alternative to improve the spectral efficiency of the CP MIMO-OFDM system. In this paper, we investigate the performance of the CP-free ST-BC MIMO-OFDM system under the effects of non-linear distortion due to HP A in the transmitter, and IQ-imbalance in the receiver. We fIrSt show that with the ST -BC encoder the constraint of the CP-free MIMO-OFDM system can be removed and back to the basic requirement of MIMO system.
