keying sequence

Keying in this sequence displays the following at the shell prompt: echo "^ [] 2; Hello^ G".

输入这个命令序列，就会在shell提示上显示以下内容：echo“^[]2；Hello^G”。

A QPSK blind sequence detection algorithm based on the ε-equalization principle is proposed. The algorithm can formulate the quadrature phase shift keying blind sequence detection into a quadratic programming with integer constraints.

给出了基于ε-均衡准则的QPSK序列盲检测算法，该算法将QPSK序列盲检测问题转化为带整数约束的二次规划问题。

Chaos masking, chaotic parameter modulation, chaos shift keying, chaotic spread spectrum sequence are discussed in detail.

其中重点分析了混沌掩盖技术, 混沌参数调制技术, 混沌键控技术和混沌扩频技术的原理.

The experimentation shows indeterminacy of chaos's time sequence in experiments of randomicity check. So the randomicity of chaos's time sequence must be checked before it become keying sequence.

实验表明混沌密码序列对随机性的测试的好坏存在不确定性，因此混沌序列应用到序列密码之前必须对序列进行随机性检测。
