“…According to the problem of high complexity of base station detection in large scale multiuser multiple input multiple output (MIMO) system,a low complexity multiuser variable node full information Gaussian message passing iterative detection algorithm based on forced convergence (VFI-GMPID-FC) was proposed.Firstly,the traditional Gaussian message passing iterative detection (GMPID) algorithm was improved to obtain VFI-GMPID algorithm,the detection performance of the VFI-GMPID algorithm approximates the minimum mean square error detection (MMSE) algorithm,but the complexity was considerably less than the MMSE algorithm.Then,the VFI-GMPID-FC algorithm was proposed to reduce the complexity of the algorithm and improve the detection efficiency.Finally,the simulation results show that the proposed algorithm can effectively reduce the algorithm complexity while ensuring the detection performance.…”

Robust adaptive beamforming algorithm by SONG Xin, WANG Jin-kuan, LIU Fu-lai, WANG Bin

“…The performance of least mean squares（LMS） algorithm degraded dramatically in the presence of even slight steering vector mismatches.In order to overcome the shortage,a novel robust adaptive beamforming algorithm based on the variable diagonal loading technique was proposed.The signal steering vector was obtained via the gradient-descent method and the diagonal loading term was incorporated at each recursive step.Then,the optimal weight vector was de-rived.To account for the contradiction of convergence rate and steady errors,a function between the step size and input signals was built to obtain the variable step size.The proposed algorithm had a low complexity cost without the inverse matrix and eigendecomposition.The proposed algorithm offered faster convergence rate,provided a sufficient robustness against the mismatches and made the mean output array SINR consistently close to the optimal one.The theoretical analysis and simulation results demonstrate that the performance of the proposed algorithm can outperform that of the conventional algorithm.…”

Polynomial estimation method for PN sequence based on reliability accumulation by Song CHEN, Kai-zhi HUANG, Hua ZHAO

“…The issues of insufficient efficiency and poor error-tolerance of current high-order polynomial estimation me-thods under error conditions were studied.By combining the iterative berlekamp-massey(BM)algorithm in GF(2)and the improved Chase algorithm,a novel algorithm based on reliability accumulation was proposed.The sequence soft infor-mation was mapped to sequence reliability as the input information of BM algorithm,and the corresponding output relia-bility of estimated polynomial was accumulated as the rule of correct polynomial.In order to improve the estimation pre-cision,the candidate reliability-accumulated polynomial set were reduced by the characteristics of primitive polynomial in GF(2).The simulation results show that the proposed method is irrelevant with the tapped number of ator poly-nomial,and has a good estimation performance to estimate 17-order polynomials when the sequence BER is 18%.…”

Influence of the optical switch’s extinction ratio on the crosstalk in fiber-optic seismometer array by Fei LIU, Xian ZHOU, Min ZHANG

“…Optical switch is one of the key components in the time-division multiplexing fiber-optic seismometer array and has significant influence on the crosstalk of the array.The source of crosstalk in the array was analyzed based on differential delay heterodyne demodulation scheme.The expression of crosstalk appearing in the seismometer’s output was deduced with the limited extinction ratio.Via simulation, the relationship between the extinction ratio of optical switch and the seismometer’s crosstalk was presented under different array scales, i.e.basically the crosstalk decreases linearly with the increase of optical switch’s extinction ratio, and increases linearly with the increase of the array scale.Finally, an 8-element fiber-optic seismometer array was set up in the experiment, on which different optical switches (acousto-optic modulator and electro-optic modulator) owning distinct extinction ratios could be applied to generate pulse light.Experimental results verified the theoretical analysis as well as the simulation results.…”
