It is shown that FRESH (frequency-shift) filtering prior to Viterbi demodulation in GSM basestations and/or handsets can multiply the number of cochannel signals that can be separated with M antennas by (2M-1)/(M-1): suppression of 1 interferer with one antenna, 3 interferers with a diversity antenna pair, and 2M1 interferers with M antennas. The network-level simulations reported in this paper clearly demonstrate that FRESH filtering prior to demodulation in GSM basestations and/or handsets…

Partially blind identification of FIR channels for QAM signals
TLDR
This work aims to improve the conventional adaptive identifier by combining blind identification/equalization techniques and the resulting adaptive identifier, which uses both, a short training sequence and the properties of the transmitted signal to estimate the channel response.
Cyclic Wiener filtering: theory and method
TLDR
The theory of optimum FRESH filtering, which is a generalization of Wiener filtering called cyclicWiener filtering, is summarized, and the theory is illustrated with specific examples of separating temporally and spectrally overlapping communications signals, including AM, BPSK, and QPSK.
Cyclostationarity in communications and signal processing
TLDR
This book brings together the latest work in the field by the foremost experts and presents it in a tutorial fashion, instrumental in furthering progress in understanding and using cyclostationarity in all fields where it arises.
Statistical spectral analysis : a nonprobabilistic theory
This book presents a general theory and methodology for empirical spectral analysis. The treatment is original because it does not make use of the difficult concept of ergodicity to provide a link
