Adaptive Algorithms For Symbol Period Estimation

by Milos Doroslovacki And, Milos Doroslovacki, Lei Yao
"... A least-mean-square (LMS) and a recursive-least-square (RLS) algorithm are derived for estimation of the symbol period in communication signals. The algorithms are based on measurements of the time elapsed between two consecutive transitions detected in noisy signals. Number of symbol periods betwee ..."

Culture in action: Symbols and strategies

by Ann Swidler - American Sociological Review , 1986
"... Culture influences action not by providing the ultimate values toward which action is oriented, but by shaping a repertoire or "tool kit " of habits, skills, and styles from which people construct "strategies of action. " Two models of cultural influence are developed, for settle ..."

, for settled and unsettled cultural periods. In settled periods, culture independently influences action, but only by providing resources from which people can construct diverse lines of action. In unsettled cultural periods, explicit ideologies directly govern action, but structural opportunities for action

Estimation of the symbol period: the frequency offset case

by Sebastien Houcke, Antoine Chevreuil, Com Elec - in XI European Signal Processing Conference (EUSIPCO , 2002
"... We address the blind equalization of a telecommunica-tion signal, the characteristics of which are totally un-known (channel, symbol period, alphabet of the sym-bols, frequency offset). In [1] was proposed a method-ology originating from deconvolution ideas, for jointly estimating the symbol period ..."

Capacity of a Mobile Multiple-Antenna Communication Link in Rayleigh Flat Fading

by Thomas L. Marzetta, Bertrand M. Hochwald
"... We analyze a mobile wireless link comprising M transmitter and N receiver antennas operating in a Rayleigh flat-fading environment. The propagation coefficients between every pair of transmitter and receiver antennas are statistically independent and unknown; they remain constant for a coherence int ..."

interval of T symbol periods, after which they change to new independent values which they maintain for another T symbol periods, and so on. Computing the link capacity, associated with channel coding over multiple fading intervals, requires an optimization over the joint density of T M complex transmitted

Joint Blind Equalization And Estimation Of The Symbol Period: A Contrast Function Approach.

by Ebastien Houcke Antoine, Antoine Chevreuil , 2001
"... The blind estimation of the symbol period of an unknown linearly modulated signal is addressed. We propose an original methodology relying on the concept of blind deconvolution, which does not suffer from the drawbacks of the classical approaches relying upon the cyclostatinarity of the received sig ..."

Performance of PCC-OFDM with overlapping symbol periods in a multipath channel

by Jean Armstrong, Tariq Gill, Chintha Tellamburat - IEEE Globecom , 2000
"... Abstract- Polynomial cancellation coded orthogonal frequency division multiplexing (PCC-OFDM) with overlapping symbol periods is a modulation technique which overcomes many of the disadvantages of OFDM PCC-OFDM is much less sensitive to frequency offset and Doppler spread than OFDM. Only the length ..."

Frequency Domain Equalization for PCC-OFDM with overlapping symbol periods

by Jean Armstrong, Jinwen Shentu, Chintha Tellambura
"... Polynomial cancellation coding (PCC) is a coding method for orthogonal frequency division multiplexing (OFDM) in which the information to be transmitted is modulated onto weighted groups of subcarriers rather than onto individual subcarriers. It has previously been shown that compared with ordinary ..."
Abstract - Add to MetaCart
the benefits of PCC-OFDM without loss of bandwidth efficiency is to overlap the transmitted symbols. At the receiver an equalizer is used to recover the data. The equalizers are two-dimensional. In this paper the results are presented for simulations of a number of different equalizer structures. It is shown
