Sample-Spaced and Fractionally-Spaced CIR Estimation Aided Decision Directed Channel Estimation for OFDM and MC-CDMA
At IEEE VTC'05 (Fall), United States.
25 - 28 Sep 2005.
The achievable performance of decision-directed channe estimation (DDCE) is analysed in the context of both OFDM and MC CDMA systems. Two different estimation methods suitable for both OFDM and MC-CDMA systems are considered, which employ sample spaced (SS) as well as fractionally-spaced (FS) a posteriori channe impulse response (CIR) estimators. The performance of both estimation methods is compared and it is shown that the DDCE scheme employing the FS-CIR estimator outperforms its SS-CIR estimator-based counter part. Furthermore, the FS-CIR estimator-based method exhibits higher robustness to various channel parameters such as the channel’s roo mean square delay spread. Finally, it is shown that the MC-CDMA system employing the channel estimation scheme advocated outperform its OFDM counterpart.
