Abstract :
The need for covert communication in tactical battlefields has developed the ideas of low probability of intercept (LPI) networks. Spread spectrum communication is used for LPI communication. Multicarrier CDMA is a new type of spread spectrum technique that has been developed in recent years. Most of the works in MC-CDMA are focused on finding out BER performance of it when different users share the same time and spectral ranges. But, LPI performance of MC-CDMA is not explored much. In this paper we have focused on understanding the LPI property of MC-CDMA. We have found out that increasing spreading factor and application of forward error control coding improve LPI property of MC-CDMA based wireless networks to a great extent.
