Comparison of the sensitivities of MC-CDMA and MC-DS-CDMA to carrier frequency offset

چکیده
In this contribution, we consider the effect of a carrier frequency offset on the performance of MC-CDMA and MC-DS-CDMA, which are both a combination of the multicarrier transmission technique and the CDMA multiple access technique. We show that both systems strongly degrade in the presence of a carrier frequency offset. Furthermore, we show that, for given spreading factor, the MC-DS-CDMA system is less (more) sensitive to carrier frequency offset than MC-CDMA when the number of modulated carriers in the former system is smaller (larger) than the spreading factor.

متن کاملComparison of Downlink and Uplink MC-DS-CDMA Sensitivity to Carrier Frequency Offsets
In this paper, we study the sensitivity of uplink and downlink MC-DS-CDMA to carrier frequency offsets, assuming orthogonal spreading sequences. For both uplink and downlink MC-DS-CDMA, we show that the performance rapidly degrades for an increasing ratio of maximum frequency offset to carrier spacing. We point out that the degradation in the uplink is larger than in the downlink, because only ...

متن کاملSensitivity of OFDM and MC-CDMA to Carrier Phase Errors
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 a...
