Abstract
Digital wireless systems employing linear modulation methods are particularly susceptible to the in-band distortions created via multipath fading. Further, this susceptibility increases, in general, as the number of modulation states increases. There is constant pressure to improve spectral efficiency as a way to increase throughput. This in turn leads to systems with higher and higher numbers of modulation states. Such systems, in addition to being highly susceptible to in-band distortion, are also susceptible to their own implementation imperfections. This makes the attainment of error rate performance close to ideal difficult to achieve. A number of highly effective techniques have been developed to address these susceptibilities. As a result, by their application, the transmission of very high data rates at very high levels of spectral efficiency is possible. In this chapter, some of the more important of these techniques that are or may be applied in wireless transport links are reviewed, including forward error correction (FEC), adaptive modulation and coding (AMC), power amplifier linearization, phase noise suppression, quadrature modulation/demodulation imperfection mitigation, and adaptive equalization.
