Thank you so much for the response.
Yes I am implementing the OFDM receiver.
So the idea is to do the serial to parallel conversion of the received signal at USRP source, So my question was, in order to do so can I use vector to streams block?? . As per the above suggestion the block does not really exist.
Instead, I can directly convert the stream output( from USRP source)to vector block for FFT implementation. Based on what the vector length and the number of items values in the stream to vector block
needs to be assigned
