Multifrequency continuous-wave–continuous-wave (MFCW–CW) radars simultaneously transmit multifrequency continuous-wave (MFCW) signals sequentially at a constant time step and a continuous-wave (CW) signal constantly. As MFCW signals are transmitt

We propose an artificial intelligence-based channel prediction scheme that can potentially facilitate link adaptation in customized communication systems. Link adaptation is a key process for wireless communication that requires accurate channel stat

A prefilter based on the time-reversal (TR) is proposed to control the multi-link interference (MLI) and the inter-symbol interference (ISI) for multi-link system. At first, we define a new parameter signal-to-sidelobe-plus-leakage ratio (SSLR) to re

For the massive Machine Type Communications (mMTC) service, a large number of devices can be connected simultaneously and the repetition signals that contain the same data can be transmitted to increase the received signal strength. Therefore, a mult

Abstract In simultaneous wireless information and power transfer system (SWIPT), additional resource allocation for power transfer degrades system performance. Therefore, how to allocate power and time to data transmission and energy transfer is very

Abstract The inter-user interference is a critical performance degradation factor in a full-duplex multi-user system. However, the conventional pre-processing filters, such as null space projection filter and regularized channel inversion filter, are
