Abstract
Summary form only given. Increasing the modulation complexity permits significant improvements in bandwidth efficiency. However, the higher level modulation schemes must include additional countermeasures to minimize increased susceptibility to dispersion, loss of threshold, further transmitter power backoff, and increased interference susceptibility
