%X This paper presents a novel power-limited pre-compensation method in MC-CDMA/TDD systems, which can avoid pilot insertion on the uplink and increase the spectral/power efficiency. To keep the transmission power constant, only the phase of signal is predistorted before transmission at the mobile station's transmitter while the amplitude estimation and compensation of received signal are performed at the base station's receiver on the uplink. The performance degradation due to the time varying channel is also included in the analysis. Simulation results show the good performance of the proposed pre-compensation method.
