Hint: the convolution is not circular in that case as we used DCT instead of DFT.
Luckily, that's not true! At the receiver, you're doing a DFT, and you've prepared the transmit signal such that a convolution with the channel looks like a circular one by prepending the CP.
The fact that the data inside has something to do with the DCT is irrelevant there.
