In book of Andrea Goldsmith, it is written that

"TDMA, FDMA, and orthogonal CDMA
are all equivalent in the sense that they orthogonally divide up the signaling dimensions, and they therefore create
the same number of orthogonal channels.In particular, given a signal space of dimension 2BT, N orthogonal
channels of dimension 2BT/N can be created, regardless of the channelization method. As a result, all multiple
access techniques that divide the signal space orthogonally have the same channel capacity in AWGN ""

Can explain me this
 

this means all have different ways(time,freq,code) of dividing the same channel in which they remain orthogonal or non overlapping so there capacity remain almost same but depends upon different issues
