QAM调制的基本原理
QAM调制实际上是幅度调制和相位调制的组合。相位 + 幅度状态定义了一个数字或数
字的组合。QAM的优点是具有更大的符号率,从而可获得更高的系统效率。通常由符号率
确定占用带宽。因此每个符号的比特(基本信息单位)越多,效率就越高。-QAM modulation of the basic principles are in fact QAM modulation amplitude modulation and phase modulation of the portfolio. Phase+ margin status defines a combination of numbers or figures. The advantage of QAM symbols are greater rate, thus the system efficiency will be higher. Symbol rate is usually determined by the occupied bandwidth. Thus each bit symbols (basic units of information) the more the higher the efficiency.

This a separate release of the OpenSS7 X/Open XTI/TLI library, TLI modules (timod, tirdwr) and the INET driver (inet) that provides Unix98 compatible interface to Linux NET4 TCP/IP stacks, and all the necessary manpages and other documentation. Although these components are contained in our LiS and Linux Fast-STREAMS releases, this tarball configures, builds and installs these components separate from those releases.
