Performance Evaluation of Uplink MC-CDMA Systems with Residual Frequency Offset
Taeyoung Kim · IEICE Transactions on Communications · 2006
This letter evaluates the performance of an uplink multicarrier-code division multiple access (MC-CDMA) system when the frequency offsets of all users are random variables and the frequency offset for the desired user is compensated. The analysis confirms that performance degradation due to frequency offset is negligible if the estimation error of normalized frequency offset for the desired user is less than 10 -1 .
