In this paper iterative interference cancellation (IIC) with Wiener filter (WF) channel estimation is proposed to eliminate the inherent intersymbol interference (ISI) and intercarrier interference (ICI) terms in Orthogonal Frequency Division Multiplex/Offset QAM (OFDM/OQAM). An iterative interference cancellation receiver is proposed using a Low- Density Parity-Check (LDPC) decoder with different patterns of scattered pilots under the effect of the timevariant LTE multipath channel. The bit error probability is compared with that of the conventional FFT-OFDM system with insufficient cyclic prefix (CP) under different environments. The results obtained show that the probability of error in the OFDM/OQAM scheme is improved in many scenarios.
