Multi-subcarrier OVSF code allocation in WCDMA

Experimental Analysis and Investigation of WCDMA Link in Terms of Error Vector Magnitude Using Vector Signal Transceiver (VST) 5644R & LabVIEW 2012

“…In this experimental Work based on VST 5644R we tried to investigate some of these simulation parameters like spreading factor of WCDMA which affects performance of the system as a whole. Using VST 5644 at Physical Layer WCDMA Link [2][3][4][5] can be implemented. This implementation includes firstly decoding the downlink modulated WCDMA received signal, analyzing the received signal pattern in software LabVIEW 2012, calculating error vector magnitude (EVM) and relative input power.…”

“…National Instruments conveys quick, adaptable, and precise RF equipment and Lab View programming to meet the regularly changing requests of the remote business and see the building procedure through from configuration to approval to generation [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. To keep pace with the continually RF development, LabVIEW graphical outline programming offers an arrangement of instruments for signal investigation, representation, and handling of standard and custom computerized and simple regulation configurations customized programming and adaptable equipment address an extensive variety of test needs including WLAN, GPS, WiMAX, MIMO, ZigBee, and RFID.…”

“…Third generation system are designed for multimedia communication at high data rate. WCDMA technology is the most widely used third generation system which is spreading over a wide bandwidth by multiplying the user information with spreading sequence in WCDMA [2][3][4][5]. Due to increasing the demand of high data rate, more complex modulation schemes are used in various wireless communications resulting tightened error vector magnitude (EVM) requirement.…”

“…Spreading factor used to support high bit rate and mitigate the effect of inter-symbol interference. The main property of the spreading code is that they need to orthogonal to each other [3], [4][5][6]. The aim of this paper is to precisely evaluate the performance of WCDMA system with different spreading factor value.WCDMA is wideband digital cellular technology used for third Generation (3G) cellular communication.…”
