... complicated. But only an algorithm is needed for the channel estimation, no matter how many subchannels the MC-CDMA system has. However, the channel- parameter estimation in the time domain is easily deteriorated ... Processing estimated channel coeﬃcients are then obtained through the two-dimensional (2D) linear ﬁltering. Other approaches [15, 16] consider an explicit channel esti...
