An overview of modulation and coding for wireless communications

An overview of modulation and coding techniques commonly used in wireless communications is given. In addition to the tutorial presentation, reference is made to a number of papers on modulation and coding options in environments typical of the land mobile channel. The characteristics of the mobile wireless channel make for a challenging design of communication systems that, in addition to the demand for good power and bandwidth efficiencies, must cope with the various degradations encountered such as adjacent channel interference, cochannel interference, fading, and multipath.
