Abstract

The main limits of the conventional single carrier modulation techniques are the restrictions imposed by the multipath channel, and the receiver complexity. On other hand the multicarrier techniques such as Multi-Carrier (MC) and Multi-Tone (MT) can provide high data rates at reasonable receiver complexities. Jamming on the other hand is of interest in some communication applications, and in military anti-jam systems. In this work, we study the performance of Multi-Tone Code Division Multiple Access (MT-CDMA) in presence of narrowband jamming. We investigate Bit Error Rate (BER) performance as a function of some system parameters such as number of sub-carriers, processing gain, and as a function of channel conditions such as jamming type, number of jammers, jamming center frequency, jamming power, and jamming to signal power ratio. We compare the performance with the analytical performance in absence of any jamming. The simulation results show, that the performance can be enhanced by increasing the processing gain, number of jammers or by decreasing the number of sub-carriers, the jamming to power ratio or jamming power. Furthermore the effect of jamming center frequency on the performance is negligible, and good agreement with the analytical performance in absence of jamming is achieved.
