This paper analyzed the spectral efficiency (total channel capacity per subband) of randomly-spread synchronous multicarrier code-division multiple-access (MCCDMA) channel subject to frequency-selective fading in the asymptotic regime of number of us

Thanks to the small wavelength at millimeter wave (mmWave) frequency, it is promising to combine massive multiple-input and multiple-output (MIMO) with mmWave. MmWave massive MIMO will differ the conventional massive MIMO, due to the differen
