Hi,

I know that USRP can send out carrier wave at one frequency. For

example, a

carrier wave at frequency 902MHz. The carrier wave sent is

sin(2*pi*902MHz*t). Can we send a carrier wave at three frequencies? For
example, a carrier wave at frequency 902MHz, 915MHz, and 928MHz. The
carrier wave I want to send
is sin(2*pi

*902MHz*t)+sin(2

*pi*915MHz

*t)+sin(2*pi

*928MHz*t). Is

multi-tone

carrier wave feasible given USRP’s hardware? How could I implement this

on

USRP? Thanks.
