Turbo demodulation of zero-padded OFDM transmissions

IEEE Transactions on Communications, 2002
We extend the turbo demodulation procedure proposed by Li and Ritcey (see IEEE Journal on Selected Areas in Communications, vol.17, no.4, p.715-24, 1999) and by Magniez, Muquet, Duhamel, Buzenac and de Courville (see Proc. Int. Symp. on Turbo Codes and Related Topics, Brest, France, p.169-72, 2000) to OFDM systems with cyclic prefix (CP-OFDM) or zero ...

The transmission zeros of systems with delays†

International Journal of Control, 1982
In this paper we study the properties of the zeros of a system with general delays in the input, state and control variables. The main result of this paper shows that the zeros of the transfer function are always zeros of the system matrix, with of at least the same multiplicity moreover, when the system is canonical, the zeros of the system matrix are

Binary transmission codes with higher order spectral zeros at zero frequency (Corresp.)

IEEE Transactions on Information Theory, 1987
A method is presented for designing binary channel codes in such a way that both the power spectral density function and its low-order derivatives vanish at zero frequency. The performance of the new codes is compared with that of channel codes designed with a constraint on the unbalance Of the number of transmitted positive and negative pulses.

Compact implementation of transmission zeros using the zero shifting property

2004 IEEE MTT-S International Microwave Symposium Digest (IEEE Cat. No.04CH37535), 2004
In this contribution we propose a structure for the implementation of transmission zeros using the zero shifting property. In previous implementations, two open loop resonators operating at different resonances were employed. In the configuration, one of the open loop resonators is substituted by a short-circuited transmission line, thus resulting into

A method for computing invariant zeros and transmission zeros of invertible systems

International Journal of Control, 1976
This paper presents a method, for determining simultaneously the invariant zeros and the transmission zeros of a large class of linear, time-invariant, invertible, multi-variable systems. The zeros are defined via the concept of minimal order system inverses.

Data transmission filters with forced zeros

IEEE International Symposium on Circuits and Systems, 2003
A description is given of the design of realizable analog data transmission filters which have as many intersymbol interference values as possible forced to zero. They possess good selectivity in the frequency domain. Their most remarkable property, however, is their simple design, the poles and zeros being given in closed form.

Assignment of Invariant and Transmission Zeros in Linear Systems

2018 26th Mediterranean Conference on Control and Automation (MED), 2018
The paper generalizes the result of Rosenbrock on the assignment of invariant and transmission zeros from systems (A, B, C, 0) with equal number of inputs and outputs to general (A, B, C, D) quadruples. The generalization, while straightforward, improves the solvability conditions and leads to a new construction of C and D matrices having least number ...

On computation of transmission zeros and transfer functions

1982 21st IEEE Conference on Decision and Control, 1982
The problem of balancing the state space system matrices of a linear time-invariant system prior to computation of its transmission zeros is considered. It is shown that in some cases balancing has a significant effect on the accuracy of the computed transmission zeros.
