 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?
