Abstract :
The paper aims at considering an alternative structure for transmitter and receiver in OFDM/OQAM systems. Such a structure is based on the frequency spreading at the transmitter and on the frequency despreading at the receiver and it is considered with reference to its implementation complexity. A modified structure is also proposed in order to reduce its computational complexity.
