A multicarrier CDMA based low probability of intercept network

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.
