Book Description
The IDA can be implemented using Reed Solomon (RS) codes. Faster and more efficient codes can be used to implement IDA, but they are not currently implemented in hardware. The IDA can be used to design bandwidth-efficient FECC for a channel with burst noise. Our research presents the analysis, design, implementation, and testing of IDA. The IDA has been implemented in software using the RS codes. We compared its performance with that of TPC. Assuming a well-defined channel with long burst noise (i.e., many bit errors) and a large block size, we showed that if symbol-by-symbol reliability is not available (i.e., unable to detect burst noise boundaries), then IDA will perform better than TPC in terms of bit and block error rates. However, if symbol-by-symbol reliability is available, then IDA may perform as well as TPC in terms of block error rate, while TPC will always have a lower bit error rate.

Book Description
One of the dramatic developments in bandwidth-efficient communications over the past few years is the introduction and rapid applications of combined coding and bandwidth efficient modulation, known as coded modulation, for error control. Using coded modulation, reliable data transmission can be attained without compromising bandwidth efficiency. Presented here are the basic concepts of coded modulation. Two simple examples are used to demonstrate how significant coding gains can be achieved without bandwidth expansion. Lin, Shu Unspecified Center NAG5-931

Book Description
"Reed-Solomon error correcting codes (RS codes) are widely used in communication and data storage systems to recover data from possible errors that occur during data transfer. A growing application of RS codes is Forward Error Correction (FEC) in the Optical Network (OTN G.709), which uses RS(255,239) to support the OTU-3 (43.018 Gbps) standard. There have been considerable efforts in the area of RS architecture for ASIC implementation. However, there appears to be little reported work on efficient RS codec (encoder and decoder) for Field Programmable Gate Arrays (FPGAs), which has increasing interests in industry. This thesis investigates the implementation and design methodology of the RS(255,239) codec on FPGAs. A portable VHDL codec is developed and synthesized for Xilinx's Virtex4 and Altera's StratixII. The FPGA architectures are analyzed and the required design methodologies are adopted to efficiently utilize the available resources. Unfortunately, due to the fixed size of FPGA devices, the RS decoder is not only constrained by the required timing of the system, but also by the size of the targeted device. This research will facilitate the decision-making process for selecting a reconfigurable device for a RS decoder, implementing the Berlekamp-Massey Algorithm"--Abstract.
