In this work, we derive a novel multicarrier modulation based on the Type-I even discrete cosine transform (DCT1e), which includes new procedures to carry out both the channel estimation and the signal reconstruction. By using a small number of train

We present a novel channel estimation technique based on discrete cosine transforms (DCT) for multicarrier and single carrier communications. Channel estimation is essential in communication systems, but especially in DCT-based transceivers for desig

In this paper, we investigate the spark of a family of transforms that are frequently used in signal processing applications such as Multicarrier Communication systems: we consider the even Discrete Cosine Transform matrices (DCTs). On one hand, we p

In this work, we address the problem of signal recovery in Multicarrier Modulation (MCM) with the Discrete Cosine Transform Type-III even (DCT3e). By appending one zero to the transmitted symbol, our technique provides a perfect reconstruction of the

In this work, we address the problem of channel estimation in multicarrier communications. We present a procedure which employs the Type-III even DCT (DCT3e) at both the transmitter and the receiver. By using any symmetric training symbol we show how

In this correspondence, the conditions to use any kind of discrete cosine transform (DCT) for multicarrier data transmission are derived. The symmetric convolution-multiplication property of each DCT implies that when symmetric convolution is perform

New extremal properties of Daubechies 4-tap orthonormal filters are given: they maximize a certain functional, have the largest gain in (0,@p/2), and allow maximum energy compaction in [0,@p/2]. These properties do not carry over to Daubechies filter
