recommendations! Published in 2023 at "IEEE Communications Letters"

DOI: 10.1109/lcomm.2023.3268031

Abstract: In non-coherent chaotic communications, traditional code-index-modulation-aided differential chaos shift keying (DCSK) schemes face limited gains in bit-error-rate (BER) performance, despite incurring substantial time-frequency resources. To address this challenge, we propose a new reconfigurable intelligent surface… read more here.

DOI: 10.1109/lwc.2023.3246132

Abstract: This letter proposes a method to approximate LoRa performance over heavy multipath channels. Firstly, the multipath time delay and LoRa signal duration are combined to analyze the path overlapping interference quantitatively. Then simple BER approximations… read more here.

DOI: 10.1109/tcsi.2023.3241929

Abstract: This study presents a wireline pulse amplitude modulation-4 (PAM-4) receiver using the least significant bit (LSB) decoding method that uses the offset of comparators. The proposed LSB decoding method can generate the same output as… read more here.

DOI: 10.1117/1.oe.64.8.088101

Abstract: Abstract. In conventional binary-modulated optical camera communication (OCC) systems, camera exposure causes inter-symbol interference (ISI), which significantly impacts bit error rate (BER) performance and limits practical applications. We apply orthogonal frequency division multiplexing (OFDM) to… read more here.

DOI: 10.11591/ijece.v11i5.pp4263-4271

Abstract: In this article, different forms of optical orthogonal frequency division multiplexing (OFDM) were observed which were suitable for optical camera communication (OCC) systems. This research aims to establish the bit error rate (BER) versus signal-to-noise… read more here.
