Abstract
We investigate the use of the discrete cosine transform (DCT) for multicarrier transmission over frequency selective channels. We derive design conditions for the DCT to diagonalize the channel into parallel, decoupled, and memoryless subchannels. Furthermore, we compare the performance of DCT and DFT-based multicarrier transceivers in the presence of channel estimation errors, residual frequency offset, and narrowband interference
