Frequency-spreading implementation of OFDM/OQAM systems
Résumé
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.
