Multiple-input multiple-output (MIMO) communication is an important technique to increase the transmission capacity, but the increased antenna number does not necessarily increase the throughput because of more antenna interference and decoding complexity. An iterative detector-and-decoder (IDD) can effectively improve transmission performance by exchanging reliability information such as log likelihood...
MapReduce greatly alleviates the burdens of programmers and gradually becomes an application programming standard on cloud computing nowadays, because the run-time system of cloud computing can automatically handle the issues of paralleled and distributed programming on behalf of programmers at run time. Although MapReduce can strongly benefit programmers on developing cloud computing applications,...
In this paper, a new generalized space shift keying (GSSK) multiple-input-multiple-output (MIMO) detector is proposed. The proposed detector improves the conventional orthogonal matching pursuit (OMP) detector by a list detection strategy, and admits a regular structure with fixed throughput characteristic. Simulation results show that our proposed list OMP detector can achieve a more favourable performance-...
In the next-generation 5G system, millimeter wave (mmWave) multiple-input multiple-output (MIMO) system utilizes massive antennas at transmitter and receiver to increase the throughput and reliability. Due to the short wavelength of mmWave signals, more antennas can be adopted to alleviate severe channel path loss. However, the increase of RF chains raises the chip cost of the transceiver. Thus, hybrid...
Spectral Embedding is one of the most effective dimension reduction algorithms in data mining. However, its computation complexity has to be mitigated in order to apply it for real-world large scale data analysis. Many researches have been focusing on developing approximate spectral embeddings which are more efficient, but meanwhile far less effective. This paper proposes Diverse Power Iteration Embeddings...
This paper presents an eye movement detection system based on EEG-based brain-computer interface (BCI). The proposed system performs feature extraction of the EEG signals and uses hidden Markov model (HMM) to perform eye movement detection. The proposed system is implemented on an FPGA board to form a real time BCI control system with a laptop. The users wearing a EEG headset can control a game on...
Lattice reduction (LR) has emerged as a popular technique to improve the performance of many low complexity MIMO detectors. Among the existing LR algorithms, the LLL algorithm has been applied to MIMO communications almost exclusively to date. However, the conventional LLL algorithm has variable reduction time, and hence non-constant throughput for the resulting communications system. In order to...
In this paper, we propose a QR-based MIMO detection algorithm and its architecture based on a non-sorted multiple-candidate selection process. The proposed multiple-candidate selection process can mitigate the error propagation problem in the general QR-SIC detection, and therefore the detection probability is increased. This algorithm requires only 24% of the computational complexity of the V-BLAST,...
