A transmit diversity scheme for channels with intersymbol interference
2000 IEEE International Conference on Communications. ICC 2000. Global Convergence Through Communications. Conference Record, 2002Alamouti (see Journal of Selective Communications, vol.16, no.8, p.1451-58, 1998) proposes a two branch transmit diversity scheme for channels without intersymbol interference. With two transmit antennas and one receive antenna the scheme provides second order diversity. In this paper we derive a new method which handles the corresponding case when the

Joint equalization and coding for intersymbol interference channels
IEEE Transactions on Information Theory, 1997Summary: We present a novel scheme that combines decision feedback equalization (DFE) with high-rate error-detection coding in an efficient manner. The proposed scheme is shown to considerably outperform the conventional practice on channels with high SNR, such as those encountered in twisted-pair telephonia systems. In order to analyze the performance

Removal of Intersymbol Interference
2018To remove the intersymbol interference I(k) defined in ( 1.42), we may not impose any constraint on the symbol sequence a(k), because the system design should hold for any sequence given by the user at the transmitter. Therefore we can only touch upon the impulse response h(k).

A parallel blind demodulator in the presence of intersymbol interference
ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002This paper proposes a demodulator employing data detectors which do not need a known sequence for its startup, i.e., a parallel blind demodulator, in the presence of intersymbol interference (ISI). This demodulator operates as follows: (1) it includes multiple adaptive maximum-likelihood sequence estimations with per-survivor processing (PSP-MLSEs ...

A random riemann zeta function and intersymbol interference
Information Sciences, 1978The probability density function (PDF) of z = Σann−α with n = 1,2,…∞ is considered where {an} are independent, identically distributed, zero mean random variables with equally likely values of ± 1. For 12 < α ⩽ 1 the series diverges; for 1 < α∞ the series converges.

Intersymbol Interference and the P/AR Meter
Bell System Technical Journal, 1970P/AR stands for peak-to-average ratio. The instrumentation to measure this ratio has been assembled and obtains a single number evaluation to the dispersion in a transmission medium by measuring the peak and the full wave rectified average of a pulse stream.1 ...

Unsupervised estimation of signals with intersymbol interference (Corresp.)
IEEE Transactions on Information Theory, 1971A decision-directed unsupervised estimation algorithm is used in a receiver that processes signals with unknown intersymbol interference. The estimator utilizes the statistical structure of this dependent sample problem to reduce the computational complexity. Asymptotic and experimental dynamic probability of error results are presented.

Differential Detection with Intersymbol Interference and Frequency Uncertainty
IEEE Transactions on Communications, 1984In this paper we study differential detection of binary differential phase shift keyed (DPSK) signals with several impairments typical in satellite communication systems. In particular, the bit error rate is determined for bit timing error and frequency offset error at the receiver.
