With the significant improvement of System-on-Chip (SoC), Network-on-Chip (NoC) is proposed to solve its communication problem. Considering that Processor Elements (PEs) are integrated into NoC, the load balance of NoC should be investigated carefully as it influences the performance of NoC mapping to a large extent. In this context, an effective mapping strategy becomes a new challenge for NoC. T...Show More
To solve the NP-difficult problem of Network-on-Chip (NoC) mapping, researchers currently use heuristic search algorithms represented by Genetic Algorithm (GA) for optimization. However, as the scale of the problem increases, the performance of these algorithms will deteriorate rapidly, and the global optimal solution cannot be obtained. Therefore, this paper proposes an improved mapping optimizat...Show More
Polar codes, as only one provable capacity-achieving channel code, have become one of the 5G standards. Belief propagation (BP) algorithm has become one of popular decoding polar codes because of unique advantage of high parallelism. But compared to the successive cancellation list (SCL) algorithm, BP algorithm still has a performance gap. This paper exploits the design of polar BP decoder using i...Show More
Filter-bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) has been considered as an alternative scheme to orthogonal frequency division multiplexing (OFDM). However, the traditional channel estimation techniques of the OFDM cannot be directly applied to the FBMC-OQAM system because of the real-field orthogonality of the FBMC-OQAM signals. Although traditional channel estimat...Show More
Most channel estimation techniques for orthogonal frequency division multiplexing system are not directly applicable to filter bank multi-carrier with offset quadrature amplitude modulation (FBMC-OQAM) system because of the imaginary interference of FBMC-OQAM system. Thus, a novel support vector regression (SVR) algorithm for fading channel estimation in FBMC-OQAM system is proposed. We propose a ...Show More
Filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) system has low out-of-band emission but needs complex receiver for broadband channel. To address this problem, we propose a new cyclic prefix (CP)-based code FBMC-OQAM system (CC-FBMC-OQAM) with low complexity in this paper. CC-FBMC-OQAM system can be realized within the framework of the standard OFDM system, and perf...Show More
Compared with the orthogonal frequency division multiplexing (OFDM) system, filter bank multi-carrier (FBMC) with offset quadrature amplitude modulation (OQAM) system has a very different time-domain signal structure: owing to the use of identical prototype filter, the data symbols of adjacent blocks overlap each other in FBMC-OQAM system. Therefore, it is not effective that we directly apply disc...Show More
Most of the peak-to-average power ration (PAPR) reduction techniques, such as partial transmit sequence (PTS) algorithm and selective mapping algorithm, for conventional OFDM systems are not directly applied to filter bank multi-carrier with offset quadrature amplitude modulation (FBMC-OQAM) systems because of the overlapping structure of FBMC-OQAM signals. Furthermore, the complexity of the exist...Show More
The intra-chip communication latency and power consumption become the main bottleneck of the development of multi-core processors. Network-on-Chip (NoC) paradigm is proposed to meet these stringent requirements. Since the wireless network interconnection can achieve high speed data transmission with low power consumption, this paper proposes a cellular NoC architecture based on multiple butterfly ...Show More
As an alternative waveforms of the fifth generation mobile communication system (5G), filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) is a powerful signal processing method that allows data transmission with a maximum bandwidth efficiency, but it still has a high peak-to-average power ratio (PAPR). In this paper, a novel algorithm for PAPR reduction is proposed by ...Show More
Scheduling applications on multi-processor is an effective core technology in using distributed systems. Task scheduling is to map applications to parallel system in order to minimize the makespan. Task scheduling is classified into static scheduling and dynamic scheduling. Most task scheduling is NP-complete problem.

Filter optimization of out-of-band emission plays an important role for FBMC-OQAM system. The main idea of this paper is to minimize the stopband energy with constraints of sidelobe and interchannel interference (ICI)/intersymbol interference (ISI) by optimizing the filter coefficients. The main contribution is that the improved approach reduces the stopband energy and suppresses the sidelobe simu...Show More
The problem of scheduling and allocation of non-preemptive strictly periodic tasks in multi-core systems mainly appears in large-scale real-time multi-core systems with strict constraints on time. Although the use of multi-core platform makes greatly improvement on computing power and reliability of electronic systems, it also enhances the complexity of the task scheduling and allocation issues. I...Show More

The networks-on-chip (NoC) architecture is an effective way to interconnect dozens of processing cores, while the logic circuits and the actual performance need to be verified in specific platform. We proposed and implemented the MACRON platform to ...Show More
