Title
Performance of downlink MC-CDMA and CI/MC-CDMA systems in the presence of narrowband interference
Abstract
MC-CDMA (Multi-carrier Code Division Multiple Access) remains a strong candidate for next generation wireless communication systems. Due to its capability of exploiting frequency diversity, MC-CDMA provides high BER performance in multi-path fading channels. In our previous work, we proposed CI/MC-CDMA (Carrier Interferometry MC-CDMA) and demonstrated better performance relative to traditional MC-CDMA using novel polyphase CI spreading codes. In this work, we evaluate the BER performance of MC-CDMA and CI/MC-CDMA systems in the presence of narrowband interference (NBI). Specifically, theoretical analysis of BER performance for both systems in a multi-path fading channel is derived. We show that the CI/MC-CDMA system provides better NBI suppression capability than MC-CDMA and offers better BER. Simulation results over frequency selective fading channels confirm the validity of the theoretical analysis.
