Abstract :
We consider a general, bandwidth efficient multicarrier transmission scheme without guard periods. Intersymbol and interchannel interferences are limited by using nonorthogonal pulses with good time-frequency localization characteristics, i.e., concentration of the energy in both time and frequency domains. This lets us derive a receiver of moderate complexity, employing iterative methods for the symbol detection. The achievable performance with the transmission and detection scheme is assessed by means of computer simulations and compared against the theoretical error rate of a corresponding interference-free transmission
