The deployment of multicarrier code division multiple access as the transmission scheme of the spectrum overlay based cognitive radio (CR) networks faces two challenging issues: (i) the need for spreading codes with arbitrary ...

data estimators. The achieved sidelobe suppression is a function

of the number of transmitted data symbols. Simulation results

show that by a slight decrease in the number of transmitted data

symbols, the sidelobes power can be suppressed...
