Abstract
AbstractIn this paper, we investigate the sensitivity of Interleaved Frequency Division Multiple Access (IFDMA) systems to phase and timing jitter. With this aim, the theoretical expressions of the Signal to Interference plus Noise Ratio (SINR) degradation are derived at the decision device input in the presence of phase and timing jitter. The obtained degradation expressions can be evaluated by means of numerical integration. They are shown as a function of the load for various parameters of jitter model. Moreover, it is demonstrated that when assuming a full load, performance degradations do not depend on data block length, compression factor and jitter spectral content as long as the transmitted data block length is large enough. Furthermore, we investigate how the Nyquist filter rolloff impacts the performance degradation. Copyright © 2007 John Wiley & Sons, Ltd.
