Spectrally Modulated Spectrally Encoded Framework Based Cognitive Radio in Mobile Environment
… such as NC-OFDM (non-contiguous Orthogonal Frequency Division Multiplexing), NC-MC-CDMA (non-contiguous multi-carrier code division multiple access) and NC-SC-OFDM (non-contiguous single carrier OFDM), allow the SUs to utilize the available spectrum. Spectrally Modulated Spectrally Encoded …

FPGA-based DOCSIS upstream demodulation
… are explored. In particular, algorithms for frequency recovery and equalization are developed. The many data-aided feedforward frequency offset estimators analyzed in the literature have not considered intersymbol interference (ISI) caused by micro-reflections in the channel. It is shown in …

Design and Optimization of 5G and Beyond Hybrid Communication Systems
… where the synchronization involves the carrier frequency offset estimation and compensation, and the calibration involves mitigating reciprocity mismatches in digital and analog RF chains of the access points (APs) implementing hybrid beamforming, enabling efficient downlink channel estimation.

Radio-Location Techniques for Localization and Monitoring Applications. A study of localisation techniques, using OFDM system under adverse channel conditions and radio frequency identification for object identification and movement tracking
… delay discrimination to improve angle-of-arrival estimation in a multipath channel with high levels of additive white Gaussian noise. A new methodology is interpreted over the multi carrier modulation scheme in which the simulation results of the estimated channel improves the performance of OFDM …
