Improvements to code dimension of evaluation codes, while maintaining a fixed decoding radius, were discovered by Feng and Rao, 1995, and nicely described in terms of an order function by Høholdt, van Lint, Pellikaan, 1998. In an earlier work, 2006, we considered a different improvement, based on the observation that the decoding algorithm corrects an error vector based not so much on the weigh...

Recent wireless communication standards such as 3GPP-LTE, WiMax, DVB-SH, HSPA and LTE / LTE advanced incorporate turbo code for their excellent performance. In this paper, we present a new 3 dimensional turbo decoder including bit error rate (BER) is much better than the 2 dimensional turbo decoder used by LTE / LTE advanced, as is illustrated by simulation. We also address the issue of the imp...

This paper addresses the application of turbo codes for third-generation wireless services. It describes the specific characteristics of high-rate data applications in third-generation wide-band code-division multiple-access (CDMA) systems that make turbo codes superior to convolutional codes. In particular, it shows the positive effect of fast power control employed in these systems on the rel...

Recently, turbo codes have received great attention due to their outstanding performance. Unfortunately, a high performance is associated with large transmission delays prohibiting an application for speech transmission. Hence, the aim of this paper is the comparison of turbo codes employing short interleavers with convolutional codes in terms of bit error rate performance and computational eff...

Near-duplicate detection is not only an important pre and post processing task in Information Retrieval but also an effective spam-detection technique. Among different approaches to near-replica detection methods based on document signatures are particularly attractive due to their scalability to massive document collections and their ability to handle high throughput rates. Their weakness lies...

In performance testing of ATM switches and network of switches a variety of connection configurations is needed. In most of the cases, these configurations require one traffic generator and/or analyzer for each switch port. Since this equipment is rather expensive, it is desirable to define scalable configurations that can be used with a limited number of generators. In this paper we present a ...

Sisvar is a statistical analysis system, first released in 1996 although its development began in 1994. The first version was done in the programming language Pascal and compiled with Borland Turbo Pascal 3. Sisvar was developed to achieve some specific goals. The first objective was to obtain software that could be used directly on the statistical experimental course of the Department of Exact...

IN SEARCH OF THE HOLY GRAIL What would a Premier League team pay for software that allowed it to optimise performance while reducing injuries? There are emerging data that would allow such software to be developed (and indeed, some software companies who already claim they can predict injuries before they occur), but no product is ready for prime time yet. In this editorial, we briefly direct t...
