1 day ago · Three challenges in achieving this are addressed: First, Chirp Spread Spectrum (CSS) modulation used by LoRa produces only hard demodulation outcomes, whereas LDPC decoding requires Log-Likelihood Ratios (LLR) for each bit. We solve this by developing a CSS-specific LLR extractor.
5 days ago · Convolutional Coding. Forward Error Correction (FEC) techniques such as the Hamming code are called block coding, because a "block" of data bits is examined to compute the required error control bits. For other applications, a method is required which is suitable for a continuous data stream.

1 day ago · This paper presents a comprehensive analysis of free space optical (FSO) communication that incorporates the orthogonal frequency division modulation (OFDM) system with differential quadrature phase shift keying (DQPSK) modulation scheme. FSO has become a significant area of research in the optical communication field due to efficient communication systems with higher data transmission rates ...
6 days ago · Forward Error Correction (FEC) is an error detection method used in data communication to detect and correct errors that occur during transmission. It involves adding redundant data to the transmitted information, which allows the receiver to detect and correct errors without the need for retransmission.
1 day ago · Like classical computers, quantum computers require error-correction schemes to reliably perform useful large-scale calculations. The nature and frequency of errors depends on the quantum computing platform, and while there has been prior work in this area based on qubit-based coding, those ideas are often not directly applicable to devices that store information in bosonic systems such as ...
