For a multiuser data communications system operating over a mutually cross-coupled linear channel with additive noise sources, we determine the following: (1) a linear cross-coupled receiver processor (filter) that yields the least-mean-squared error between the desired outputs and the actual outputs, and (2) a cross-coupled transmitting filter that optimally distributes the total available power among the different users, as well as the total available frequency spectrum. The structure of the…

Blind cancellation of co-channel interference

To prevent the receiver from locking on to the same signal more than once, the determinant constant-modulus algorithm is proposed, which can outperform other known methods, as demonstrated by simulation.

We present, by extension of some earlier results, the expression of an upper bound on the bit error rate (BER) of a digital communication system operating on a frequency selective channel linking N

Optimum diversity combining and equalization in digital data transmission with applications to cellular mobile radio. I. Theoretical considerations

A comprehensive theory for Nth-order space diversity reception combined with various equalization techniques in digital data transmission over frequency-selective fading channels is developed and is applied to optimize system parameters and to predict performance for QAM data transmission operating over a model for the mobile radio channel.

Transmitter design for data transmission in the presence of a data-like interferer

When applied to HDSL-like systems with a single (or dominant) interferer, this work confirms that wider-than-Nyquist transmitters provide a large performance advantage over Nyquist-limited transmitters, and explains why PAM and QAM systems operating at the same spectral efficiency do not perform identically over the crosstalk channel.

Design of filterbank transceivers for dispersive channels with arbitrary-length impulse response

The proposed algorithm allows a straightforward transmitter design and generally yields a near-optimum solution for the transmit filters, and a link to minimum mean squared error designs for a similar setting is established.

Multichannel Signal Processing

A transmitterheceiver pair is proposed that compensates for crosstalk by treating an entire bundle of twisted pairs as a single multiinput~ultioutput channel with a (slowly varying) matrix transfer function.

Optimum linear diversity receivers for mobile communications

The results show that, under certain conditions, the optimum linear receiver can almost completely eliminate all ISI and CCI while providing near-optimum noise filtering.

Optimization for crosstalk suppression with noncoordinating users

A joint transmitter/receiver optimization problem for multiuser communications in a symmetric crosstalk environment based on the minimum mean squared error (MMSE) criterion is addressed and the performance advantage obtained by exploitation of the cyclostationary nature of the interference is demonstrated.

We consider an MxN MIMO system transmitting orthogonal multicodes from each antenna. A time-dispersive channel causes the codes to de-orthogonalize, complicating the detection problem. A chip-level

Zero forcing equalizing filter for MIMO channels with intersymbol interference

It is shown, that an optimal time lag in the filter will improve the performance considerably and the general structure of the linear zero forcing equalizing filters for multiple input multiple output (MIMO) communication systems with more outputs than inputs is derived.



The optimum linear modulator for a Gaussian source used with a Gaussian channel

It is shown that the commonly held notion that when the source and channel dimensionalities are equal the optimum modulator is linear and requires a block length of only one is incorrect except in very particular situations which are described.

A linear coding for transmitting a set of correlated signals

The coding theory can be extended to include the minimization of the expectation of any positive definite quadratic function of the differences between the original and reconstructed signals.

Capacity of the Gaussian channel with memory: The multivariate case

A formula is derived for the capacity of a multi-input, multi-output linear channel with memory, and with additive Gaussian noise that shows that channel capacity and cable length are linearly related; for small signal-to-noise ratio, capacity and length are logarithmically related.

A Determinant Maximization Problem Occurring in the Theory of Data Communication

Let H be a Hermitian $m \times m$ matrix, with eigenvalues $\lambda _1 \geqq \lambda _2 \geqq \cdots \geqq \lambda _m \geqq 0$ of which $m^ + \geqq 1$ are positive. Then the maximum of $\det ( {I_n +

Linear equalization theory in digital data transmission over dually polarized fading radio channels

For the dually polarized radio channel, it is found that linear equalization structures can practically eliminate the effects of cross-polarization interference contributed by the antennas and their feeds.
