PSK 星座点选择
在 PSK,所选择的星座点通常与周围一圈的统一角间距定位。这样的腐败因此最佳的免疫和相邻的点之间的最大相分离。他们被放置在一个圆圈,以便他们可以所有传输具有相同的能量。这种方式,它们表示的复数的模量将是相同的因此因此将余弦和正弦波所需的振幅。两个常见的例子是"二进制相移键控"(BPSK),使用两个阶段,和"求积相移键控"(QPSK),使用四个阶段,虽然可以使用任意数量的阶段。由于通常二进制数据来传达,PSK 计划通常设计有的正在 2 的电源的星座点的数量。

The Joint Video Team (JVT) of ISO/IEC MPEG and ITU
The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for
the coding (compression) of natural video images. The new standard [1] will be known as H.264 and
also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding:
Context-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC).
The Variable-Length Coding scheme, part of the Baseline Profile of H.264, is described in this
document.
