This paper proposes a strategy that combines user pairing and spectrum allocation for a Virtual Multiple-Input Multiple-Output (V-MIMO) Single-Carrier Frequency-Division Multiple Access (SC-FDMA) transmission over Inter-Symbol Interference (ISI) channels. The users are equipped with a single antenna each, where always two users, composing one pair, transmit their data in the same time slot and frequency band. The receiver at the Base Station (BS) is assumed to have multiple antennas and separates the users of each pair with a multiuser equalizer.
