研究采用大单元间距非周期阵列的方法抑制和避免栅瓣，并在单元级非周期阵列形式的基础上研究适合于大型相控阵的子阵级非周期阵列形式，给出几种非周期阵列的形式及相应的波瓣图(study the method of aperiodic array using big space of elements to suppress and avoid the grating lobe, and study the forms of aperiodic array in the sub-array level which are suitable for large phased array on the base of the aperiodic array in the element level )

AWGN信道下，基于16QAM的TCM编译码(AWGN channel, 16QAM-based TCM encoding and decoding)

实现分段拟合处理数据，达到实现文中的可调式程序的目的，实现了数据处理的可能性(Fitting the data to achieve piecewise)

BCH码simulink仿真，可以用作simiulink初步学习的例子。(BCH code simulink simulation, can be used as a preliminary study simiulink example.)

Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference and jamming, and to prevent detec
