Abstract
In this paper, we present a novel multicarrier spread spectrum (MC-SS) system based on filter bank theory. We refer to our system as filter bank MC-SS (FB-MC-SS). The system parameters that lend themselves to an efficient implementation are identified, and the relevant signal processing blocks are accordingly developed. The developed FB-MC-SS system is realized on a software radio platform and the experimental results are compared against those of its direct sequence spread spectrum (DS-SS) counterpart. Our experiments demonstrate a variety of jamming conditions where FB-MC-SS outperforms the conventional DS-SS by a significant margin.
