    Improved transmit beamforming design based on ADMM for low probability of intercept of FDA-MIMO radar by Pengcheng GONG, Yuntao WU

    Published 2022-04-01
    “…Considering the low probability of intercept problem that the signal-dependent interference and the target were located in the same angle, an improved transmit beamforming design based on the alternating direction method of multipliers (ADMM) was proposed for multiple-input multiple-output with frequency diverse array radar.The transmit energy was minimized at the target under constraints of the energy at each transmitter and signal clutter-plus-noise ratio requirement.Subsequently, a cyclic algorithm was developed to tackle the non-convex design problem.Firstly, the optimal receive filter was obtained by generalized Rayleigh quotient.And then the transmit beamforming was optimized by employing auxiliary variables and ADMM to solve quadratic programming problem with fractional inequality constraint.Moreover, both the convergence and computational complexity of the proposed algorithm were discussed.Simulation results show that, compared with the semi-denite programming method, the proposed method not only attains the given antenna power, but also achieves the better mainlobe focusing performance at the target.Furthermore, the null levels at the clutter locations and the jamming directions obtained by the proposed method are -50 dB above.…”

    Polarization-based puncturing pattern selection of shortened Polar code by Shunlan LIU, Aiming HU, Jianrong BAO

    Published 2019-02-01
    “…In order to solve the problem of inflexible Polar code length,a new puncturing pattern selection scheme based on feedback cost puncturing was proposed to generate shortened Polar codes.In this scheme,the Polarization effect was reserved,the sub-optimal subchannel was selected as the cost bit,the output bit corresponding to the cost bit was used as the puncturing pattern,and then the value of the cost bit is adjusted by feedback to obtain the shortened Polar code.Simulation results show that the performance of the proposed shortened Polar code is better than that of the shortened Polar code generated by bit-reversal permutation method,and the shortened Polar codes generated by direct puncturing method at the end under different channel and code rate conditions,and slightly weaker than that of the shortened Polar code proposed by Wang R and Liu R et al.In the AGWN channel,when the block error rate is 10<sup>-3</sup>,the proposed shortened Polar code with a code rate of 0.5 can obtain a gain of 0.5 dB compared with the shortened Polar code generated by bit-reversal permutation method,and the coding performance is greatly improved.…”
