Although many approaches for iris recognition have been proposed in the last few years, few of them can perfect well in various image qualities. A novel method for iris recognition based on feature fusion is presented. Global and local iris features are extracted to improve the robustness of iris recognition for the various image quality. To represent the(More)
This paper presents a design of 8B/10B encoder and decoder with a new architecture. The proposed 8B/10B encoder and decoder are implemented based on pipeline and parallel processing. The decoder implements an error-undiffusing function. This 8B/10B encoder and decoder can be used in the high-speed interconnection between chips. After being synthesized using(More)
In this paper we proposed a fully-parallel irregular LDPC decoder which uses only registers to store the temporary intrinsic messages. Our decoder adopts a simplified min-sum algorithm to reduce the hardware implementation complexity and area, and due to the factor modification we achieve a negligible performance loss compared with the general min-sum(More)
Recently, narrowband Internet of Things (NB-IoT), one of the most promising low power wide area (LPWA) technologies, has attracted much attention from both academia and industry. It has great potential to meet the huge demand for machine-type communications in the era of IoT. To facilitate research on and application of NB-IoT, in this paper, we design a(More)
