Hi all, I have a USRP N210 and DBSRX2 daughter board, running on Ubuntu 10.04, and I would like to get the L1 signal by
using Gnuradio Companion to draw a GPS receiver flow graph (I have a GPS Antenna), and I just need to get the IF signal into File Sink to get the .dat so I can use MATLAB to deal with the data, I have a book "A Software-Defined GPS and Galileo Receiver: A Signal-Frequency Approach", there is a GNSS L1 front-end digram at p.55 (that is my only reference), but I have no idea how to translate it into GNUradio Blocks.There is a ADC on that diagram, should I just ignore it, or I need some blocks to complete that ADC? (There is no blocks called ADC)And there is several Band-Pass Filter in the diagram with center frequency and 3dB Bandwidth, but I don't know how to translate it to the information that blocks needed.(Like Low or High cutoff frequency, transition width ...etc) Can anyone help me? Or has an example .grc or some website for related information? Thanks, Eddie
