Mitigation of transceiver bandwidth limitations using multi-subcarrier signals

Abstract

In this paper we demonstrate a low-complexity pre-emphasis technique for electronic subcarriermultiplexed signals to mitigate transceiver bandwidth limitations. As opposed to traditional FFT/FIR-based preemphasis techniques, we propose a simple and effective power-ratio optimization between electronic subcarriers that requires only 1 real multiplication per subcarrier.
