Block-by-Block Channel and Sequence Estimation for ISI/Fading Channelsnable complexity and perform well even in fast changing environments. The algorithms work on a block-by-block basis and utilize periodically, but sparsely inserted known data symbols. In producing their channel estimates, however, the algorithms do make use of the information contained in the receiv

A New Analysis Method for the Performance of BandPass Sampling Digital Demodulators Considering IF Fhifting and the suppression of noise and spurious signals. The bandpass sampling technique can simplify the front-end processing of a digital receiver by eliminating RF downconversion stages. In addition, as the signal is sampled prior to downconversion to baseband, accurate conversion can be perfor

Comparison of Demodulation Techniques for MSKpproach combined with feedforward phase synchronization, whereas the second algorithm, block demodulation, is based on minimizing a distance measure based on the symbol vector trial and the observed differential phase vector. The third algorithm is based on the same distance measure, however the min

The Bootstrap Decorrelating Algorithm: A Promising Tool for Adaptive Separation of Multi-User CDMA Sy, particularly in regions where interference energies are low. Adaptive structure of this separator termed “Bootstrap” is suggested in this paper and is shown to be suitable in situations where the cross-correlation matrix is unknown, or the codes have been altered by the channel.

A New Analysis Method for the Performance of BandPass Sampling Digital Demodulators Considering IF Fmed without the usual analog circuit problems of carrier I/Q phase offsets, amplitude imbalance and carrier feed-through. In this paper the effects of aliasing on the noise density at baseband and the effect of the BPF on the wanted signal characteristics are analysed.
