[edit] Yellow marking pf P-to-S and S-to-P in the figure

The picture is wrong in my opinion, since P-to-S and S-to-P are also needed for regular OFDM-systems. —Preceding unsigned comment added by 129.69.173.180 (talk) 09:27, 20 March 2008 (UTC)

In practice, the FFT and IFFT algorithms can take a parallel form as input (a vector of elements saved in a buffer, which will be read out of order), and output serial form (an ordered sequence of elements). Alternatively the algorithm may input serial form, and output parallell form. But still, there is no difference between SC-FDMA and OFDMA in this sence. Mange01 (talk) 20:54, 31 March 2008 (UTC)

[edit] Single-carrier frequency domain equalization (SC-FDE)

What is the difference from single-carrier frequency domain equalization (SC-FDE)? In what sence is this a multiple access/channel access method such as OFDMA, i.e. for several users? SC-FDE is only a digital modulation method based on inverse multiplexing and multiplexing, correspodning to OFDM? Mange01 (talk) 20:54, 31 March 2008 (UTC)
