Abstract: For future mobile radio communication system we are in need of high spectral efficiency, high mobility with wide band transmission. For this purpose Orthogonal Frequency Division Multiplexing (OFDM) combined with Multiple Input Multiple Output (MIMO) becomes one of the powerful promising technique. The algorithm proposed in this paper can suppress Inter Carrier Interference (ICI). The performance of Progressive Parallel Interference Canceller (PPIC) is compared with the performance of Parallel Interference Canceller (PIC). The Bit Error Rate (BER) versus Signal to Noise Ratio (SNR) for both the algorithms is also analyzed. PPIC has several advantages over PIC such as complexity, system architecture etc.

Keywords: Bit error rate (BER), Inter carrier interference (ICI), Orthogonal Frequency Division Multiplexing (OFDM), Multiple input multiple output (MIMO), Progressive parallel interference canceller (PPIC), Parallel interference canceller (PIC), Signal to noise ratio (SNR).
