Comments on "High-Throughput, High-Performance OFDM via Pseudo-Orthogonal Carrier Interferometry Spreading Codes

The "pseudo-orthogonal carrier interferometry orthogonal frequency-division multiplexing" technique proposed by Wiegandt can be obtained by simple rearrangement of the parallel data. Thus, the resulting system is not orthogonal frequency-division multiplexing any more, and can be regarded as a cyclic-prefix-based single-carrier system, and the reduction of the peak-to-average-power ratio is not a result of the proposed complex technology
