EN Efficient utilization of electromagnetic spectrum is the key for supporting the growing number of wireless applications and wireless users requiring access to this limited natural resource. To accommodate this ever increasing growth, spectral agile waveforms can be employed in order to fill in any frequency “white spaces” left unoccupied by primary user transmissions. Despite their numerous advantages, spectrally agile waveforms possess several technical challenges that require creative solutions, especially with respect to the minimization/elimination of out-of-band interference, implementation complexity reduction, synchronization, and digital pre-distortion. This chapter introduces the reader to several innovative approaches for achieving a practical spectrally agile waveform design that can enable more efficient use of wireless spectrum from a secondary user perspective.
