Abstract Details

2008, Master of Science (MS), Ohio University, Electrical Engineering (Engineering and Technology).
Digital Video Broadcasting - Return Channel over Satellite (DVB-RCS) Turbo Codes have become increasingly popular because of their ability to provide an uplink and downlink on the same path. However, the hardware implementation of these codes remains a challenge to the engineers and designers. This research focuses on the implications of quantizing a decoder's input to achieve a significant improvement in the hardware implementation of the decoding architecture. The performance issues related to the quantization have been studied in detail. An approach to achieving performances very close to the floating point methodologies has been presented in the form of an algorithm. Results show that by sacrificing very little performance, cost effective and optimal hardware designs can be obtained.
