Precoding and modulation are important modules in wireless transmissions. Precoding designs improve the spectral efficiency and system performance in multi-input multi-output (MIMO) systems. Modulation is the process of varying one or more properties (amplitude, phase, and/or frequency) of a carrier signal, with information, e.g., bits, to be transmitted. Existing modulation methods for wireless communication primarily […]

An algorithm reducing cost, time, and increasing efficacy over current detection systems. It is applicable for detecting cybercrime, for supporting GRC initiatives, as well as to identify cyberbullying and self-harm, including suicidal thoughts. Existing algorithms and detection systems based on them typically depend on manually developed dictionaries and / or require a large number of […]
