The effect of carrier phase jitter on variable rate CI/MC-CDMA performance

In this work, we investigate the sensitivity to carrier phase jitter of a phase-locked local oscillator on the performance of variable rate CI/MC-CDMA system over non-dispersive channel. It is shown that for full load, the degradation depends on the jitter variance and non-orthogonality among the spreading codes of the users. When all the subcarriers have same power level and jitter spectrum, the degradation caused by the jitter variance and cross-correlation variance varies from user set to user set in variable rate transmission schemes.
