180KHz or 200KHz in GSM? - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.


 Post subject: 180KHz or 200KHz in GSM?
Posted: Tue Jul 20, 2004 2:08 am 
when we calculate noise in GSM system, we consider bandwidth as 200KHz
but in some document it is 180KHz as "equivalent noise bandwidth".
so input noise or KTB=120.85dBm or -121.3dBm.
I think when we consider all system include baseband we use 180KHz instead of 200KHz, right?
Any clear answer about this?
