Abstract
A novel spread spectrum (SS) system based on the unconventional self encoding principle has been proposed for highly secured data transmissions. This system inherits the antijamming (AJ) and low probability of interception (LPI) characteristics like any other SS system with the aid of truly random spreading codes, which are generated from the source stream itself. Therefore, the proposed system is unique in that the traditional transmit and receive PN code generators are not needed. In fact, the enhanced transmission security arises not only due to the SS nature of the signal, but also from the true randomness of the unique spreading processes. This paper describes the proposed system and presents the simulation results of the system performance under various kinds of jamming conditions, which is not been so far dealt. The obtained performance curves are compared with existing SS systems like direct sequence and frequency hopped SS.
