This letter studies slow, fast and opportunistic fluid antenna multiple access (FAMA) under the effect of Nakagami-$m$ fading channels, considering the new and realistic spatial block-correlation model. Expressions for the outage probability (OP), based on the signal-to-interference ratio (SIR), are derived for slow FAMA. Interestingly, we provide mathematical relationships that allow the expressions of fast FAMA to be obtained from slow FAMA. Multiplexing gains for an opportunistic FAMA (O-FAMA) network are presented for both slow and fast FAMA scenarios. Our analytical results are validated through Monte Carlo simulations, under various channel and system parameters. All expressions derived in this letter are original.
