In this paper, the authors propose a new LInear amplification system using Nonlinear Components (LINC) transceiver that utilizes a modified architecture. The drawbacks of the conventional LINC transmitter, which are related to the power efficiency loss due to the analog Radio Frequency (RF) signal recombination at the LINC output stage, are avoided by combining the decomposed LINC signals digitally at the receiver. Simulation results using a commercial amplifier with a Raleigh fading channel and 802.11a signal demonstrated an obvious improvement of the power efficiency.
