whitepaper A protocol analyzer shows the user what is happening on the network by decoding the different protocols that devices on the network use to communicate, and presenting the results in human-readable form.
[12 Apr 2008]
whitepaper When the Alamouti code is applied (as a space-time block code) to an OFDM system with transmit diversity, the simple Alamouti decoding requires that each subchannel is flat-fading and constant over two symbol periods (Alamouti codeword period).
[10 Apr 2008]
whitepaper Both joint decoding and single-user decoding are considered. This paper presents some new results on large-system CDMA obtained through the replica method developed in statistical physics. It is found that the spectral efficiency of randomly spread...
[10 Apr 2008]
whitepaper Orthogonal frequency-division multiplexing (OFDM) converts a frequency-selective fading channel into parallel flat-fading subchannels, thereby simplifying channel equalization and symbol decoding. However, OFDM's performance suffers from the loss...
[10 Apr 2008]
whitepaper Indeed, the gain in performance brought by the robustness of ZP-OFDM to channel zero locations is amplified by iterative decoding. This paper has extended the turbo-demodulation procedure to ZP-OFDM by accounting for the noise color introduced by...

whitepaper The authors approach improves upon an existing technique by incorporating a simple chrominance coding that allows overall image quality on par with the state of the art, but at a substantially lower encoding and decoding complexity.
[28 Mar 2008]
whitepaper The partition function pertaining to finite - temperature decoding of a (typical) randomly chosen code is known to have three types of behavior, corresponding to three phases in the plane of rate vs.temperature: the ferromagnetic phase...
[14 Feb 2008]
whitepaper This paper examines methods, based on the popular Viterbi algorithm, for Maximum-Likelihood (ML) decoding of this convolutional code within the WLAN baseband receiver. Standards for the operation of Wireless Local Area Network (WLAN) technology in...
[05 Dec 2007]
whitepaper An alternative is to send and receive over an IP network, by encoding and decoding the audio from a Data Terminal Set (DTS) that is part of the normal operational equipment. Link-11 is a tactical digital communication network standard deployed in...
[05 Dec 2007]
whitepaper The new headend and associated systems support content acquisition and delivery, MPEG-4/MPEG-2 encoding and decoding, and digital content and network management. TEO LT, AB Group is the largest fixed-line telephony and Internet related services...
[16 Nov 2007]
whitepaper The goal is to perform speaker modeling and identification without decoding the speech bitstream to extract speaker dependent features, thus saving important system resources, for instance, in mobile devices.
[06 Aug 2007]
whitepaper This paper presents a combined channel decoding architecture for 3G terminal applications. Channel coding is a key element of any digital wireless communication system since it minimizes the effects of noise and interference on the transmitted signal.
[01 Aug 2007]
whitepaper The paper analyzed the factors which lead to the performance degradation in heuristic decoding scheme where inverse MCTF is carried out in spatial lowpass wavelet domain as if it were the original video at encoder.
[25 May 2007]
whitepaper Work by Ho et.al demonstrates that random network coding can solve this problem at the high cost of jointly decoding the source and the network code. The work discussed in this paper considers the problem of distributed source coding of multiple...

whitepaper Moreover, MoViF manages to apply an elegant strategy to minimize the overall power consumption for all the receivers while improving their decoding quality by dynamically assign the tasks of aid information extraction to some intermediate powerful...
[24 May 2007]
whitepaper This new scenario imposes real-time, synchronous decoding and rendering requirements which are difficult to achieve be-cause of the intrinsic complexity of video and the resource constraints such as processing power and battery life of mobile...
[23 May 2007]
whitepaper Generally, this kind of conversion, transcoding, requires full decoding and reencoding. This paper proposes an efficient algorithm for conversion of an MP3 stream into Advanced Audio Coding (AAC). However, the re-encoding based transcoding process...
[23 May 2007]
whitepaper For such schemes, low decoding complexity for correcting (or recovering) storage node failures is essential for practical systems. Proper data placement schemes based on erasure correcting code is one of the most important components for a highly...
[23 May 2007]
whitepaper The basic Pyramid Codes are simply derived from any existing codes (preferably MDS codes), and thus all existing work on optimizing encoding/decoding directly apply. This paper describes flexible schemes to explore the tradeoffs between storage...
[23 May 2007]
whitepaper This paper presents a novel high-efficient Hybrid Open-Close loop based Fine Granularity Scalable (HOCFGS) coding framework supporting different decoding complexity applications. The open-loop motion compensation for inter-pictures is introduced to...
