Multicarrier and single-carrier communications can be performed by using different orthogonal transforms. In this work, we derive the conditions to use discrete cosine transform type-IV even (DCT4e) in these contexts. Basically, these conditions are the two following: 1) The channel impulse response has to be symmetric. 2) Redundancy (a prefix and also a suffix guard sequence) must be appended into each data symbol to be transmitted. To satisfy the former, a front-end prefilter must be… CONTINUE READING
