N-continuous OFDM signal analysis of FPGA-based transmissions

Abstract

N-Continuous OFDM systems have been proposed to achieve an important reduction of the out-of-band emitted power compared to conventional OFDM. However, system complexity has been increased and some resource demanding operations are necessary. So, this work considers the implementation in FPGA of the transmitter and also provides a novel analysis on the influence of the IFFT length in the representation of the continuity condition. Spectral measurements are practiced in the model to evaluate the performance.
