Abstract

Iterative decoding has been widely used to achieve reliable high data rate transmission for broadband multi-carriers communication systems. However, in Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems with insufficient cyclic prefix (CP), there are significant challenges for efficient receiver design under the effect of the time-variant Long-Term Evolution (LTE) multipath channel. It means that the system performance may be degraded due to the inter-symbol interference (ISI) and inter-carrier interference (ICI) resulting from other transmitted signals. In this work, iterative interference cancellation (IIC) and MIMO-IIC with linear and successive interference cancellation (SIC) detection schemes are proposed using a Low-Density Parity-Check (LDPC) decoder for MIMO filter bank multicarrier/offset QAM (MIMO-FBMC/OQAM) and MIMO-OFDM systems. IIC and MIMO-IIC are used to calculate the ICI/ISI components from the estimated decoded signals and remove them from the received signals. SIC is used to reduce the cross interference from the other antenna. The bit error probability is compared with that of the MIMO-OFDM system with insufficient cyclic prefix (CP) under different environments. The results obtained indicate that IIC and MIMO-IIC can effectively mitigate error floors introduced by channel variation and insufficient CP with high bandwidth efficiency. With SIC detection, a second order diversity is approximately achieved.
