Sensitivity of OFDM and MC-CDMA to Carrier Phase Errors
نویسندگان
چکیده
In this contribution, we investigate the effect of carrier phase errors on the performance of orthogonal frequency division multiplexing (OFDM) and multicarrier code-division multiple access (MC-CDMA). We show that OFDM and MC-CDMA have essentially the same sensitivities to carrier phase errors. A constant carrier phase offset yields no degradation of the system performance. We show that OFDM and MC-CDMA are quite sensitive to a carrier frequency offset : the degradation caused by this impairment is an increasing function of the number of carriers. Carrier phase jitter on the other hand gives rise to a degradation that is independent of the number of carriers, but only depends on the jitter variance.

The Sensitivity of a Flexible Form of MC-CDMA to Synchronisation Errors
In this contribution, we propose a variant of the MC-CDMA system that offers more flexibility than the traditional MC-CDMA system. We investigate the sensitivity of this flexible MC-CDMA system to some types of synchronisation errors. This flexible MC-CDMA system is not affected by a constant phase offset or a constant timing offset, as in the proposed flexible MC-CDMA system the carriers insid...
متن کاملSynchronization sensitivity of multicarrier systems
In this paper, we give an overview of the sensitivity of a number of multicarrier systems to carrier and clock synchronization errors. A comparison is made between orthogonal frequency division multiplexing/multiple access (OFDM(A)) and two combinations of the orthogonal multicarrier technique and the code-division multiple access (CDMA) technique, i.e., multicarrier CDMA (MC-CDMA), where the s...

متن کاملThe Sensitivity of MC-CDMA to Synchronisation Errors
In this contribution, we investigate the sensitivity of MC-CDMA systems to synchronisation errors. We show that the signal-to-noise ratio (SNR) of the MC-CDMA system at the input of the decision device in the presence of a carrier frequency offset or a clock frequency offset is a rapidly decreasing function of the number of carriers. For a maximal load, carrier phase jitter and timing jitter gi...
متن کاملAn Overview of MC-CDMA Synchronisation Sensitivity
This paper presents an overview of the effect of synchronisation errors on MCCDMA performance in downlink communications. We distinguish two types of synchronisation errors: carrier phase errors and timing errors. We show that the MC-CDMA system is very sensitive to a carrier frequency offset or a clock frequency offset. For a maximal load, carrier phase jitter and timing jitter give rise to a ...
