where X is frequency-domain input vector, [T.sup.-1] is IDFT matrix.
Frequency domain signal [[??].sub.H] is transformed by means of IDFT in time domain unequalized signal [[??].sub.H].
where [n.sub.d] is the arrival time difference between the two signals from BS 1 and BS 2, [g.sub.1] and [g.sub.2] are the IDFT's of [H.sub.1] (k) and [H.sub.2] (k), respectively.
To maximally show the superiority of compressive sensing theory, we focus on the performance of CQI feedback compression based on CS by using IDFT in our experiments.
Compared to the conventional OFDM, DFT-S OFDM scheme contains one more DFT operation in the signal modulation and one more IDFT in the signal demodulation.
