Hi,
I wonder if any of you guys knows a method to decode uplink GSM signals. I
have previoulsy used Airprobe to decode downlink signals, but it does not
work with uplink signals. I was using the following scheme:
USRPN210--->gsm-receiver/gsmtvoid>gsmdecode/Wireshark
My approach is to modify
Hi,
I am dealing with a UMTS uplink receiver implementation with USRP N210. I
have some general questions that I hope that someone can answer:
1) Is it completely necessary to implement a rake receiver? I have been
reading quite a lot about it, and it seems extremely complex because it
needs cha
Hi!
I am trying to implement an UMTS uplink scanner with GRC. My purpose is to
detect the activity of channels by sensing the spectrum and comparing the
measured power against a certain threshold. The blocks that I am using are:
uhd_usrp_source--->root raised cosine filter---power
squelch--
