Hello,
I'm student and I've been told that adding no payload symbols (no useful information) to a signal increases the BER. For example in OFDM, if I add a cyclic prefix to a useful information (in matlab add the end of the vector to the beginning) will increase the BER.
However, the BER is...
Hello,
I try to understand how the CMU200 perform a location update. Basically, in GSM, this is done by communicating thanks to the SDCCH logic channel, on the SDCCH physic channel.
Like this:
location update request (MS) ---> (BS)
authentification request <---
authentification response --->...
Indeed. Finally, the aim of this setting is only to counterbalance the path loss, right? In this configuration, I can check if the power comply with GSM specifications. Do I understand?
Hello,
it is written in the CMU200 documentation that we can add some attenuation on the RF output. "The softkey Ext. Att. Output defines an external attenuation (or gain, if the value is negative) at the selected RF output."
However I get gain if the value is positive, I've checked it with...
Hello Folks,
I have to design an assignment about 2G for students. I need to use the R&S CMU200 (mainly used to simulate a 2G/3G base station). I got some problems about the synchronization between the mobile station and the base station. I'm looking for someone who know the CMU 200 and could...
