| dc.description.abstract | In this paper, rejection of multiple narrowband interferers in a binary phase shift keying modulated orthogonal fre- quency division multiplexing (BPSK-OFDM) system is investigated. The BPSK-OFDM system in consideration oper- ates in an additive white Gaussian noise (AWGN) channel. A cascade complex coefficient adaptive infinite impulse response (IIR) notch filter with gradient-based algorithm is used to reject the interferers. Bit error ratio (BER) perform- ance of the system is studied and a general closed-form expression is derived assuming negligible steady-state leakage NBI and by estimating the decision variable as Gaussian distributed based on Central Limit Theorem (CLT). Depend- ence of the BER performance on the notch bandwidth coefficient is demonstrated by the analysis. Extensive simulation results are included to substantiate accuracy of the analysis. | |
