Trellis-Based Extended Min-Sum Algorithm for Non-Binary LDPC Codes and its Hardware Structure

Autor: Kiran Gunnam, David Declercq, Erbao Li

Publikováno v: IEEE Transactions on Communications
IEEE Transactions on Communications, Institute of Electrical and Electronics Engineers, 2013, 61 (7), pp.2600-2611. ⟨10.1109/TCOMM.2013.050813.120489⟩

In this paper, we present an improvement and a new implementation of a simplified decoding algorithm for non-binary low density parity-check codes (NB-LDPC) in Galois fields GF(q). The base algorithm that we use is the Extended Min-Sum (EMS) algorith

Low-Power VLSI Design of LDPC Decoder Using Dynamic Voltage and Frequency Scaling for Additive White Gaussian Noise Channels

Autor: Kiran Gunnam, Euncheol Kim, Weihuang Wang, Gwan Choi

Publikováno v: Journal of Low Power Electronics. 5:303-312

This paper presents an adaptive LDPC decoder design that dynamically adjusts performance to optimize gain/power for additive white Gaussian noise (AWGN) channels. The proposed decoding scheme provides constant-time decoding and thus facilitates real-

Vision-Based Sensor and Navigation System for Autonomous Air Refueling

Autor: Monish Tandale, John Valasek, Declan Hughes, John L. Junkins, Kiran Gunnam, Jennifer Kimmett

Publikováno v: Journal of Guidance, Control, and Dynamics. 28:979-989

Autonomous in-flight aerial refueling is an important capability for the future deployment of unmanned aerial vehicles, because they will likely be ferried in flight to overseas theaters of operation instead of being shipped unassembled in containers

A vision-based DSP embedded navigation sensor

Autor: Nasser Kehtarnavaz, Declan Hughes, Kiran Gunnam, John L. Junkins

Publikováno v: IEEE Sensors Journal. 2:428-442

Spacecraft missions such as spacecraft docking and formation flying require high-precision relative position and attitude data. Deep space missions require the use of alternative technologies. One such technology is the vision-based navigation (VISNA
