Fast Heuristics for Power Allocation in Zero-Forcing OFDMA-SDMA Systems with Minimum Rate Constraints

Diego Perea-Vega, Andre Girard, Jean-Francois Frigon

We investigate in this paper the optimal power allocation in an OFDM-SDMA system when some users have minimum downlink transmission rate requirements. We first solve the unconstrai…
