Modulation classification, an intermediate process between signal detection and
demodulation in a physical layer, is now attracting more interest to the cognitive radio field …

In multiband transmitters where two or more radios share the same power amplifier (PA),
interferences can usually be kept below an acceptable level with the help of multi-band …

In this paper, we leverage the power of artificial intelligence in the receiver design for joint
baseband demodulation and channel decoding. We consider a point-to-point …

To address the low spectrum efficiency of satellite communications, faster-than-Nyquist
(FTN) signaling has proven a promising technology to improve the spectrum efficiency …

Communication signal modulation recognition refers to a process of automatically
processing a received signal and determining its modulation type. As an intermediate part of …

Direct sequence spread spectrum (DSSS) signals are widely used in various military and
civilian communication systems. It adopts the pseudorandom (PN) sequence to modulate …

Specific transmitter identification (SEI) is a technology that uses a received signal to identify
to which individual radiation source the transmitted signal belongs. It can complete the …

In this paper, a low complexity demodulation scheme is proposed for IEEE 802.15. 4 LR-
WPAN systems. In the proposed scheme, multiple active correlators for demodulation are …

In this article, a real-time digital predistortion (DPD) hardware architecture is presented for
the linearization of fifth-generation (5G) transmitters with wideband modulation signals. To …

In the scenarios of non-cooperative wireless communications, automatic modulation
