Abstract: In this letter, we propose a multilevel coded modulation (MLCM) scheme based on single parity check (SPC)-aided spatially coupled low-density parity-check (SC-LDPC) codes to enhance spectral ...
Escalating from last month’s internal warnings of rough vibes, OpenAI CEO Sam Altman has declared a company-wide “Code Red” to salvage his flagship product. As a result, the “Pulse” personal assistant ...
Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...
Astronomers are puzzled, and that’s putting it mildly. A strange pattern of pulses, repeating like clockwork, has been detected from 3I/ATLAS, an interstellar object cruising through our Solar System.
Abstract: The polar-coded OTFS system is applicable to high-speed mobile communication scenarios. However, the interplay between polar code and OTFS modulation ...
