Abstract

In this paper, the performance of an exponentially modulated filter bank based multicarrier (FBMC) modulation is compared with a cyclic prefix based OFDM (CP-OFDM). Both frame and bit error rates (FER/BER) are evaluated using the ITU-R vehicular-A channel model and LDPC forward error correction coding. For FBMC, a low complexity per-subcarrier equalizer called AP-ASCET is utilized to perform channel equalization. Simulation results indicate that, compared to FBMC, CP-OFDM requires about 1.5 dB higher source E_b/N_o to operate on same information rate at frame error rate of 10^-1 and bit error rate of 10^-3, respectively
