The autocorrelation demodulator (ACD) for DDPSK is an offset tolerant demodulator which
has been introduced for applications where the signal experiences large Doppler shift …

Carrier frequency offset (CFO) and time-varying fading channels are two problems that
emerging ultra-narrowband solutions for Internet of Things and Wireless Sensor Networks …

A DFT-based demodulator for BFSK is used for applications where the received signal
experiences a carrier frequency offset (CFO) much larger than the data rate. It is particularly …

A baseband differential-detection receiver for DPSK, incorporating a planar extended
Kalman filter for Doppler frequency offset estimation and compensation, is presented …

Information is an important feature of modern warfare. In the information warfare network,
unmanned aerial vehicle (UAV) relay communication has caused research interest in many …

The issue of frequency offset in low data rate, narrowband and low power communication
nodes is considered in this paper. To avoid power hungry precise frequency generation …
