摘要: In this paper, the power loading problem for orthogonal frequency division multiplexing (OFDM) with imperfect channel estimation is investigated considering trade-off between energy efficiency (EE) and spectral (SE). Unlike traditional research that uses EE as an objective function imposes constraints either on SE or achievable rate, we propound a multiobjective optimization approach can flexibly switch functions change priority level of each using parameter. Our dynamic more tractable than conventional approaches convenient to realistic communication applications scenarios. The system model considers path loss shadowing effect in modeling metrics, addition taking error into account. We first solve marginal problems maximizing individuality, then prove equivalent simple maximizes capacity minimizes total consumption. Finally, use numerical results discuss choice parameter study error, transmission budget channel-to-noise ratio optimization.
