In this letter, the multiuser bit and power allocation problem for an orthogonal frequency division multiplexing (OFDM)/offset-quadrature amplitude modulation (OQAM) system is investigated. The signal-to-interference-plus-noise ratio (SINR) and required power expressions for the formulation of the problem in an OFDM/OQAM system are developed. Next, a suboptimal algorithm based on this formulation is proposed.
