Hello all,We want to transmit two channels OFDM signal. Each channel has 500kHz bandwidth.
We want to connect each channel to TAP interfaces. At the end, we have two OFDM receivers and two OFDM transmitters. We are getting trouble with putting tags these two streams (from TAP0 and TAP1). The messages that comes from TAP0 and TAP1 interfaces are different sized. We have combined these two OFDM TX paths using "Tagged Stream Mux". The disadvantage of this block is that it waits length tag from both of the inputs, so we can send data when both of the interfaces are active. But we should also send when one of the channels is active.
The GNU Radio FG is attached. So, how can we send multiple tagged streams to USRP device? Does using Tagged Stream Mux is true approach for this task?
You may suggest another approach. Best regards. Ramazan
