Re: [Discuss-gnuradio] What is the difference between Streams To Stream and Streams to Vector

[Richard Bell]

Hi Carl,

I can't answer the question for you directly, but I can give you a way to figure it out.

Use two vector source blocks to generate two different known streams. The first stream vector would be [1,3,5,7,...], a list of odd numbers however long you want to make it. Set the block to repeat this. The second vector would be [0,2,4,6,...], a list of even numbers. Feed these two streams into your Streams to Vector block and dump it to a file. Now inspect the file and see how these two streams were merged together.

Hope that helps.

Hi all!

I am recording data from two USRP:s and I want to put the data into one file sink.

I think I could do it by using the Streams To Vector block and then changing the vector parameter in the file sink to 2.

1) How would I read that data in e.g. Matlab. Right now I am using the read_complex_binary function when I don't have a vector input. Is the format the same just that every second variable is from element 2 of the vector input?

2) There is also the Streams To Stream block. What would the difference be if I connected that block to the two USRP source blocks and then the output to a file sink, would that be the same as in Q1?

3) Could I read myself to this information anywhere?

Thank you very much!

Best Regards,

Carl
