Whitepaper: Analysis of Cellular Interference for MC-CDMA and Its Impact on Channel Estimation

by American Enterprise InstituteJan 01, 2008

MultiCarrier (MC) modulation, in particular Orthogonal Frequency Division Multiplexing (OFDM), has been successfully applied to various digital communications systems. OFDM can be efficiently implemented by using the Discrete Fourier transform (DFT). This paper from AEI addresses the downlink of a cellular Multi-Carrier CDMA (MC-CDMA) system taking into account channel estimation. The system performance in presence of a synchronization mismatch between two interfering Base Stations (BS) is analyzed in the way that a mobile terminal receives the perfectly synchronized signal from the desired BS as well as the signal from one interfering BS with a synchronization offset.
