This work presents a low-complexity hardware implementation of highly accurate wide-band Gaussian noise generator based on the Ziggurat method. Different from the previous works in the literature, the Ziggurat Algorithm is modified such that the computations are done over only three equal regions, yielding important savings in the resource utilization. For the verification of the design, Chi-square...
This paper presents the usage of the Reed Solomon Codes as the Forward Error Correction (FEC) unit of the Hybrid Automatic Repeat Request (ARQ) methods. Parametric and flexible FPGA implementation details of such Erasure-Only RS decoders with high symbol lengths (e.g. GF(232)) have been presented. The design is based on the GF(2m) multiplier logic core operating at a single clock cycle, where the...
This paper presents a generic RAM based FPGA architecture for decoding of Multi Rate Quasi-Cycling LDPC codes. RAM based decoding enables us to reduce permutation networks into simple address controllers. Moreover, utilizing Block RAMs with various aspect ratios in an FPGA provides flexibility ranging from area driven compact designs to fully parallelized high throughput designs. Utilizing the read-first...
This paper presents a simplified SpaceWire network architecture to overcome a challenging high-speed and real time packet switching process required in a baseband processing unit of a regenerative satellite payload as a part of the “On-Board Processing EHF (Extremely High Frequency) Satellite Transponder and Testbed Development Project”. This is an R&D Project supported by the Scientific and Technological...
