Performance enhancement of slot synchronization in W-CDMA

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

“…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.…”

“…The NI Vector Signal Transceiver combines radio frequency Input/output functionality in traditional box which contain Vector Signal Analyzers (VSAs) and Vector Signal Generator (VSGs) along with user defined functionality implemented on Field Programmable Gate Array (FPGA). The two independent local oscillators used for RF input and RF output coverage from 65 MHz to 6 GHz and bandwidth up to 200 MHz [5].The bandwidth requirement of WCDMA [8][9][10] is based on 5 MHz wide RF radio signal and generally use chip rate of 3.84Mcps. WCDMA technology is designed to be a high-performance system able to support high bandwidth and requiring simultaneous transmission of several bit streams that require different requirements of quality of service (QoS).…”

“…The scrambling codes [4] are responsible for the most of the interference as these codes are not orthogonal. The channelization codes [6][7][8][9] may also result in interference as their orthogonality may be lost due to propagation environment. This work is based on experimental and real time implementation of WCDMA Link based on PXIe VST 5644 platform [1].The objective of the proposed experimental based research is to design and optimize an WCDMA link using VST 5644R and evaluate the performance of the proposed WCDMA link at different system parameters like scrambling code, spreading factor, modulation scheme e.g-QPSK, QAM.…”
