Hi, any insight to these queries?

1) Which come first at the transmitter - cyclic prefix or pulse
shaping? Reason I ask this is if cyclic prefix is done first, won't
the pulse shaping destroy the structure?

2) Which pulse shapes are used - RC or RRC? Is a corresponding matched
filtering required at the receiver? Reason I ask this is some
literature seem to imply that a matched filter is not necessary at the
receiver.

Thanks!
