Multi-mode filter bank solution for broadband PMR coexistence with TETRA

Fast convolution processing has recently been proposed as an efficient means for implementing filter bank multi-carrier systems with good spectral containment and high flexibility in tuning the subchannel bandwidths and center frequencies. These features make fast convolution filter banks (FC-FBs) a particularly interesting choice for multi-carrier transmission in challenging radio scenarios like dynamic spectrum access, cognitive radio, and fragmented spectrum use. In this contribution, the target is to study the performance of the FC-FB approach in heterogeneous radio environment. The focus is on the use of FC-FB for simultaneous processing of FB multi-carrier waveforms and narrowband TETRA signals.
