In this paper, we propose and compare some design criteria for the search of good rate-compatible turbo (RCPT) codes families. The considerations presented in [1] to find “best” component encoders for turbo codes construction are extended to find the “best” rate-compatible puncturing patterns for a given interleaver length . This approach is shown to be the optimal one, both in the maximumlikel...

This work describes a method for providing robustness to errors from a binary symmetric channel for the JPEG2000 image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets. Punctured turbo codes are used for the channel coding, providing stronger error protection than previously available codes. We use a subset of the puncturing patterns ...

Carnitine palmitoyl transferase 2 (CPT-2) is a key enzyme in the mitochondrial fatty acid metabolism. The active site is comprised of a Y-shaped tunnel with distinct binding sites for the substrate acylcarnitine and the cofactor CoA. We investigated the thermodynamics of binding of four inhibitors directed against either the CoA or the acylcarnitine binding sites using isothermal titration calo...

This study is an attempt in exploring the feasibility of low-grade kaolinite clays, generated as waste from excavation works, supplementary cementitious materials and potential candidate for cement replacement. Clays five sources were investigated composition, pozzolanic reactivity effect on mortar strength durability. grinded calcined at 700 °C to convert into metakaolin. Thereafter, 30% by wt...

Abstract In unequal error protection (UEP) schemes, the bits are protected according to their significance in terms of distortion reduction capability during reconstruction process. The conventional UEP schemes primarily designed either using forward correction at application layer network architecture, or hierarchical modulation physical layer. this paper, an optimized cross-layer scheme for s...

Multiple-input multiple-output (MIMO) multiplexing is an attractive technique to achieve very high-speed transmission with a limited bandwidth. Recently, we proposed an iterative frequency-domain interference cancellation (FDIC) for single-carrier MIMO (SC-MIMO) multiplexing. In our previous work, assuming that the interference from the other antennas can be perfectly cancelled in FDIC, one-dim...

We develop a Wyner-Ziv still image codec with decoder feedback, based on a Rate Compatible Punctured Turbo (RCPT) code. Within this framework, two methods of pairing source data with side information are compared and found to be similar in performance. The architecture is modified into a Wyner-Ziv image codec with rate estimation at the encoder. The proposed rate estimator is the mean of the tu...

Bluetooth has emerged as a viable COTS alternative for military applications involving low power wireless networks, including wireless sensor networks and personal area networks for the foot soldier. However, the reachability of Bluetooth networks is limited by the weak error control coding used by the predefined packets. In this paper, we propose a method for improving the performance of Bluet...

The need for optimised utilisation of scarcely available radio resources is prevalent. An efficient use of radio resources could lead to higher spectral efficient transmission on wireless channels. A promising scheme for wireless multimedia transmission at a lower cost is adaptive modulation and coding (AMC). In this paper, a new scheme for AMC is devised. A prioritized adaptive CDMA modulation...
