Abstract
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 full
transmission/reception process of data in Type-II even DCT and Type-IV even
DCT-based systems. The paper focuses on the use of symmetric extension (SE) and
zero padding (ZP) as redundancy methods. Furthermore, three cases related to
the channel order and the length of the redundancy are studied. In the first
case, 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 of
the redundancy; the interference caused by the channel impulse response is
calculated, and theoretical expressions for their powers are derived. These
expressions allow studying the achievable data rate of DCT-based MCM systems,
besides enabling the comparison with the conventional MCM based on the discrete
Fourier Transform.
