An analysis of the effect of chip timing jitter in MC-CDMA systems

In this paper, we investigate the effect of chip synchronization error (or chip timing jitter) in a multicarrier-code division multiple access (MC-CDM A) scheme, The chip timing jitter is modeled by a stationary random process with a known statistic, and the error produced by the jitter is reduced to an additive source of noise. This decomposition is useful because it allow s for the use of analytical methods for the computation of the error probab ility, First, the analysis has been applied to the simple Gaussian channel; afterwards, it has been extended to a multipath fading channel typical of large indoor areas. Use of a semi-analytical approach has been the key fact or in obtaining reliable results at moderate computational complexity.
