Block Sizes

Interleaver is an indispensable component in the design of Turbo encoder and Turbo Decoder. QPP interleaver is a 3GPP specified conflict free interleaver for turbo channel coding scheme for all code block sizes of 40 to 6144. Thus the efficient design of a conflict free reconfigurable QPP interleaver for turbo encoder and turbo decoder is a pre-eminent task in turbo channel coding scheme. In this article, Design of a simplified reconfigurable (40 to 6144 block sizes) Recursive QPP interleaver for computation of address locations to minimize the computational complexity and to avoid storage of interleaver tables has been presented. The proposed interleaver will be further integrated in the design and implementation of high throughput parallel turbo decoder. The proposed design is synthesized and implemented using 28nm CMOS technology Zynq Zed FPGA and achieved low processing timing constraints, utilization and power constraints compared with other conventional designs.

Research Studies

This research studies the concept and application of the Turbo_encoder to be an integrated module in the In-Vehicle Device (IVS) embedded module by using the magnitude comparator. To create the Turbo_encoder Module, the complex PLDS are used. The variants of series and parallel Turbo_encoders are discussed. It is shown that proportional to chip size processing time also increased in the Turbo_encoder parallel computing variant system. The magnitude comparator with parallel computing variant system is implemented in this project. The usage of proposed logic resulted in efficient area and power usage. The architecture construction using Verilog HDL and implementation and simulation are executed in the Xilinx-ise tool. To incorporate the built module, Xilinx Vertex Low Power is used. The Turbo_encoder module on a single programmable computer is planned to be part of the IVS chip.

Design And Implementation

Purpose To provide an overview of communication characteristics exhibited by individuals with Angelman Syndrome (AS) and special considerations associated with the design and implementation of augmentative and alternative communication (AAC) programs. Method Results of recent studies exploring individuals' uses of AAC are reviewed, with particular emphasis on factors related to individuals' acceptance and successful uses of AAC systems. Results Not applicable Conclusion Despite their inconsistent access to practices previously found to foster individuals' acceptance of AAC systems, individuals with AS demonstrate the ability to use AAC systems, including high-tech AAC devices, successfully.
