Performance Analysis of a Low-Interference N-Continuous OFDM Scheme
share
This letter analyzes the performance of a low-interference time-domain N-continuous orthogonal frequency division multiplexing (TD-NC-OFDM) scheme for sidelobe suppression in terms of power spectrum density (PSD) and bit error rate (BER). Firstly, an asymptotic closed-form expression of the PSD is derived for describing the rapid sidelobe decaying of the low-interference TD-NC-OFDM signal. Then, an asymptotic expansion of BER is achieved for the received signal over the multipath channel. Simulation results confirm the accuracy of our performance analysis.
