Co-channel and Adjacent Channel Interference
Measurement of UMTS and GSM/EDGE Systems in 900 MHz Radio Band

Abstract. This paper is concerned with inter-system and
intra-system interference measurements of 2.5G and 3G
mobile communication systems. The both systems UMTS
and GSM/EDGE are assumed to operate in a common
radio band of 900 MHz. The main system parameters are
briefly introduced as well as the measurement scenario.
Several simulations and key measurements were performed.
Important results are described and commented
along with a graphical representation, namely bit error
ratio (BER) dependence on carrier to noise ratio (CNR) in
the presence of additive white Gaussian noise (AWGN), the
measurement of adjacent channel interference ratio of
each system, the coexistence of both systems in same band
and the impact of a carrier offset on BER.

at least we still have problem in GSM system and very important thing about interference of frequency rather different to WCDMA system
