Development of Zero-Padded Conjugate Cancellation Transmission with Adaptive Receiver for ICI Cancellation

Amandeep Kaur, Garima Saini

OFDM (Orthogonal Frequency Division Multiplexing) system is the high bandwidth efficient technique mainly used for high data transmission over the multipath fading environment. The major challenges faced by OFDM/OFDMA systems are sensitivity to frequency selective fading and ICI due to Doppler shift and CFO when subcarrier spacing becomes smaller. So we implement the zero padded conjugate technique with Adaptive receiver to cancel out the ICI. Adaptive receiver has the frequency tracking capability by adopting the normalized block least mean-squared algorithm. Zero padding makes the signal more robust to errors and also increases the subcarrier spacing. In this paper proposed design methodology is discussed in detail and performance is evaluated for AWGN fading channel for BPSK, QPSK and 16-QAM modulation techniques in terms of BER.

Keywords: Block least mean-squared BLMS algorithm, frequency offset, inter-carrier interference ICI, orthogonal frequency division multiplexing
