The ACFTU, Labor Law, and Labor Reform codes. We also define a corresponding key equation and concentrate on decoding alternant codes when . is a domain or a local ring. Our approach is based on minimal realization (MR) of a finite sequence [.,.], which is related to rational approximation and shortest linear recurrences. The resulting

The Political and Economic BackgroundDetermining the weight of Boolean functions is of exponential complexity. By using combinatorial results, it is proved that from their algebraic normal form (ANF), it is possible to have polynomial time results on the weight, for some classes of functions. As a result, the structure of the majority functions .. is given.

Applications of Exponential Sums in Communications Theory,We provide an introductory overview of how exponential sums, and bounds for them, have been exploited by coding theorists and communications engineers.

An Encoding Scheme for Dual Level Access to Broadcasting Networks,irect-sequence spread spectrum communications are implemented to add specific information to the signal within the bandwidth allocated for broadcasting. This is beneficial to both the service providers and all subscribers in the network since the information added can advertise programmes which many are not yet authorised to access.

An Overview of the Isoperimetric Method in Coding Theory (Extended Abstract) [Invited Paper],hold behaviour has been studied in many situations outside coding theory and a number of tools have been developped. One of those turns out to be particularly relevant to coding, namely the derivation of isoperimetric inequalities for product measures on Hamming spaces. we discuss this approach and derive consequences.

Rectangular Basis of a Linear Code,he rectangular complement operation. The notions of rectangular closure and basis were already defined. In this paper we represent a method to construct a rectangular basis of a linear code from a given linear basis.

Catastrophicity Test for Time-Varying Convolutional Encoders,ally efficient algorithm to determine whether or not a time-varying convolutional encoder is catastrophic is derived. This algorithm is shown to be simpler than the catastrophicity test proposed by Balakirsky [.]. Furthermore, the algorithm can easily be generalised to rate . time-varying convolutional encoders.
