| Abstract: | In contrast to the classical spread spectrum or data encryption methods, we propose an array redundancy-based approach for wireless transmissions with inherent low probability of interception (LPI). The redundancy of transmit antenna arrays introduces some degrees of freedom for deliberate signal randomization, based on which, diversity is exploited to randomize the eavesdropper's signal. LPI is analyzed by proving the indeterminacy of eavesdroppers' blind deconvolution. Extensive simulations and preliminary experiments are conducted to demonstrate the proposed method. | ||
