• Significant advances in basic research to
  provide a foundation for designing high
  information-capacity wireless communication
  systems for full mobility will require
  synergistic, multidisciplinary research efforts
  encompassing a breadth of communications
  functions from the physical through application
  layers.

MCM for Next Generation Wireless

• Next generation wireless systems are
  characterized by their high demand on
  adaptability to a wide range of channels and
  traffic conditions and patterns
• Multi-carrier modulation (MCM) is an attractive
  candidate for satisfying this demand (DMT, OFDM,
  MC-CDMA, )
• Optimization of MCM functions can be handled
  together with network and application functions
  (PAR, channel modeling,)
