One of the most important key technologies for digital communication systems as well as
storage media is coding theory. It provides a means to transmit information across time and …

Encoders for convolutional codes with large free distances can be constructed by combining
several less powerful convolutional encoders. This paper is devoted to constructions in …

In continuation to an earlier work, where error exponents of typical random codes were
studied in the context of general block coding, with no underlying structure, here we carry …

Concatenation of several conventional convolutional encoders is a both powerful and
practical method to obtain encoding schemes that are attractive for use in communication …

We consider convolutional and block encoding schemes which are variations of woven
codes with outer warp. We propose methods to evaluate the distance characteristics of the …

An upper bound on the error probability (first error event) of product convolutional codes
over a memoryless binary symmetric channel, and the resulting error exponent are derived …

In this correspondence, the error exponents and decoding complexity of binary woven
convolutional codes with outer and inner warp are studied. It is shown that for both …

The invention relates to a system for transmitting data according to the frequency hopping
method. The digital data, which is transmitted in suddenly changing transmission frequency …

In this paper, we present an input-state-output representation of a convolutional product
code; we show that this representation is non minimal. Moreover, we introduce a lower …

In this paper, we first provide an overview of the woven convolutional codes (WCC) and an
iterative decoding scheme for WCC. Then we present a new coded wavelet based …
