Dataset for Compressed Impairment Sensing Assisted and Interleaved-Double-FFT Aided Modulation Improves Broadband Power Line Communications Subjected to Asynchronous Impulsive Noise

Abstract

In power line communications (PLCs), the multipath-induced dispersion and the impulsive noise are the two fundamental impediments in the way of high-integrity communications. The conventional orthogonal frequency-division multiplexing (OFDM) system is capable of mitigating the multipath effects in PLCs, but it fails to suppress the impulsive noise effects. Therefore, in order to mitigate both the multipath effects and the impulsive effects in PLCs, in this paper, a compressed impairment sensing (CIS)-assisted and interleaved-double-FFT (IDFFT) aided system is proposed for indoor broadband PLC. Similarly to classic OFDM, data symbols are transmitted in the time-domain, while the equalization process is employed in the frequency-domain in order to achieve the maximum attainable multipath diversity gain. Additionally, a specifically designed interleaver is employed in the frequency-domain in order to mitigate the impulsive noise effects, which relies on the principles of compressive sensing (CS). Specifically, by taking advantage of the interleaving process, the impairment impulsive samples can be estimated by exploiting the principle of CS and then cancelled. In order to improve the estimation performance of CS, we propose a beneficial pilot design complemented by a pilot insertion scheme. Finally, a CIS-assisted detector is proposed for the IDFFT system advocated. Our simulation results show that the proposed CIS-assisted IDFFT system is capable of achieving a significantly improved performance compared to conventional OFDM. Furthermore, the tradeoffs to be struck in the design of the CIS-assisted IDFFT system are also studied.
