Effect of Co-Existence Interferences on QoS of HSPA/WCDMA Mobile Networks
Original language description
The rising density of wireless networks and the related rising number of user equipment increase the vulnerability of interference generation. These interfering signals could be generated as the result of the co-existence of wireless standards like DVB-T, LTE, WCDMA, WiMAX, GSM, Wi-Fi and other services transmitted in adjacent bands of the radio spectrum. The received signals are mixed with the higher order modulation products on the nonlinearity of amplifier. Next, the generated interfering signals areradiated back to the radio environment. With sufficient power the mixed signals could overlay an inter or intra system channel and thus interfere useful signals of surrounding transmissions. This paper introduces the influence of interfering signals ontransmission parameters in the 3G HSPA mobile network. Our measurement is carried out in a real 3G UMTS network using HSPA user equipment. The bandwidth of interfering signals is chosen in compliance with the possible scenarios generating
