AB This paper aims at studying the achievable data rate of discrete cosine transform (DCT)-based multicarrier modulation (MCM) systems. To this end, a general formulation is presented for the fulltransmission/reception process of data in Type-II even DCT and Type-IV evenDCT-based systems. The paper focuses on the use of symmetric extension (SE) andzero padding (ZP) as redundancy methods. Furthermore, three cases related tothe channel order and the length of the redundancy are studied. In the firstcase, the channel order is less than or equal to the length of the redundancy.In the second and third cases, the channel order is greater than the length ofthe redundancy; the interference caused by the channel impulse response iscalculated, and theoretical expressions for their powers are derived. Theseexpressions allow studying the achievable data rate of DCT-based MCM systems,besides enabling the comparison with the conventional MCM based on the discreteFourier Transform.
