Reconstruction of Frequency Hopping Signals From Multi-Coset Samples
Multi-Coset (MC) sampling is a well established, practically feasible scheme for sampling multiband analog signals below the Nyquist rate. MC sampling has gained renewed interest in the Compressive Sensing (CS) community, due partly to the fact that in the frequency domain, MC sampling bears a strong resemblance to other sub-Nyquist CS acquisition protocols. In this paper, we consider MC sampli...
متن کاملAdaptive Use of Spectrum in Frequency Hopping Multi-Band Transmission
A method to achieve high data rate transmission in a wireless military communications system is proposed. The scheme operates by periodically measuring energy over the span of the transmission band, and identifying spectral areas with low jammer and/or interference energy. A probabilistic algorithm is then used to adaptively define spectral regions in which a frequency-hopped spread-spectrum (F...
متن کاملAdaptive Frequency Hopping for Multiuser OFDM
This paper presents adaptive frequency hopping as a new user allocation scheme for multiuser OFDM. Users are allocated carriers that have the highest SNR of available system carriers. This process is updated regularly to track channel fading. Adaptive frequency hopping greatly reduces frequency selective fading, improves interference rejection, and consequently improves the received SNR. Additi...
متن کاملAdaptive De-Noising of Low SNR Signals
In 1992 David Donoho has introduced the term de-noising. Despite its advantages, this method isn't used yet in communications. The goal of this paper is to adapt this method to the requirements of communications, especially for low SNR signals. Our contribution is a new threshold's value search method, that realizes the maximization of the signal to noise ratio at the output of the de-noising s...
متن کاملMulticarrier CDMA with Adaptive Frequency Hopping for Mobile Radio Systems
A modified multicarrier (MC) direct-sequence code-division multiple-access (DS-CDMA) system has been proposed for use over slow multipath fading channels with frequency selectivity in the reverse link transmission of a cellular network. Instead of transmitting data substreams uniformly through sub-channels, data substreams hop over subchannels with the hopping patterns adaptively adjusted to th...
