The research on wireless communications has received many attentions. The underlying physical channels may be characterized as time-varying fading channels. In this chapter, we will study communications over fading channels from an information-theoretic point of view. Many state-of-the-art coding and modulation schemes, including space-time codes, will be introduced

实际信道中,大多数具有带通传输特性,必须用数字基带信号对载波进行调 制,产生各种已调数字信号。可以用数字基带信号改变正弦型载波的幅度、频率 或相位中的某个参数,产生相应的数字振幅调制、数字频率调制和数字相位调制。 也可以用数字基带信号同时改变正弦型载波幅度、频率或相位中的某几个参数 产生新型的数字调制
