Abstract

In this paper, Orthogonal Frequency Division Multiplexing (OFDM) spectrum shaping using various techniques to reduce Adjacent Channel Interference (ACI) is investigated. The trade-offs between interference level and spectral efficiency, power consumption, and computational complexity are discussed. Simulation results along with detailed analysis showing the advantages and disadvantages of each technique are presented. © 2008 IEEE.
