Efficient Intercarrier Interference Mitigation for Pilot-Aided Channel Estimation in OFDM Mobile Systems [PDF]

, 2011
Motivated by the possibility of decreasing the intersymbol interference (ISI) which is due to large delays of a multipath mobile radio channel, orthogonal frequency division multiplexing (OFDM) became very popular. However, the timevariance of the mobile

On Iterative Detection, Demodulation and Decoding for OFDM-CDM [PDF]

, 2006
In this paper, we address iterative receiver processing for OFDM code division multiplexing (OFDM-CDM). The receiver algorithm we focus on is soft parallel interference cancellation in combination with a-priori demodulation.
