高机动雷达T型方舱和机柜滑架的设计考虑

介绍为高机动雷达研制的T型方舱的结构设计特点,以及方舱内机柜滑架的应用情况。T型方舱是一种承栽／自重比较高的小型、非标准大板方舱,是为适应高机动雷达总体结构的高度集成而研制的专用方舱;安装于T型方舱内的机柜滑架,可将2个装有雷达主设备的综合设备机柜整体连动滑出进行维修,其应用使空间受制约的T型方舱也具有良好的维修性和操作使用的舒适性。     

A Novel Least-Entanglement-Assisted Asymmetric Quantum Codes Based on Sliding Grill

We propose new methods for constructing novel entanglement-asslsted asymmetric quantum codes based on combinatorial designs and sliding grill. Based on a special case of combinatorial designs, our proposed method can construct a type of parity check matrix with greater column weight and better decoding performance. Combined with the characteristic of asymmetric quantum chan- nel, we propose new method of sliding grill. Mother matrix and submatrix can be constructed. The null space of the parlty-check matrix gives entanglement-asslsted asymmetric quantum code. Tanner graph of the code has a girth of at least 6. Our proposed quantum code has higher code rate with the same error correction capability. These families of entanglement-asslsted asymmetric quantum codes consume only one copy of maximally entangled state （ebit）, and outperform other quantum codes based on similar construction method according to our numerical computation.
