Hello sorry for the last message thought i attached my screenshot results at first. I am having some problems as to whether the information from the cdma transmission and reception are accurate. I have posted my screenshots for clarification hopefully.http://imageshack.com/a/img633/757/Yx8B7r.png The first screenshot is from executing the "cdma_txrx.grc" which seems to test well I believe because moving the sliders around and threshold I am able to notice when it performs tracking and acquisition of the signal automatically.
http://imageshack.com/a/img631/8451/CDqdTM.png The second screenshot is me loading two USRP's. This is the execution of the "cdma_tx.grc file with the UHD:USRP Sink and its WX GUI FFT Plot. My issue here is the FFT plot doesn't look right to. By the way the channel model for this is AWGN. http://imageshack.com/a/img538/7792/1xXqN4.pngAfter running the "cdma_tx.grc" file, I proceed to go to my other laptop and run the "cdma_rx.grc" file which is connected to that USRP(UHD USRP SOURCE. The image above is what I get. In the beginning it seems to be acquiring the packets then a few seconds later a lot of invalid packets get detected. Overall all are these images close to what I should be seeing.
