Inter-carrier Interference Self-Cancellation Scheme with Improved Bandwidth Efficiency for OFDM Transmission Systems

摘要

This paper presents a bandwidth efficient interference self-cancellation scheme in OFDM systems with no overhead symbols utilized. This scheme uses a simple data precoding prior to intercarrier interference self-cancellation modulation. Performance comparison shows that the proposed scheme is comparable to conventional self-cancellation schemes, while significantly increasing throughput and bandwidth efficiency.
