چکیده
In Universal Mobile Telecommunication System (UMTS), high data rate transmission is possible by using Wideband Code Multiple Access technique (WCDMA) as an air interface. This paper studies performances of various modulation schemes such as Phase Shift Keying(both BPSK and QPSK) and M-ary Quadrature Amplitude Modulation (M-ary QAM) in WCDMA downlink transmission to improve its data rate. Based on Bit Error Rate (BER), performances of various modulation schemes have been investigated. The Simulation tool SIMULINK is used to evaluate BER in WCDMA system.

متن کاملUsing WPT as a New Method Instead of FFT for Improving the Performance of OFDM Modulation
Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...

In today communication network the major challenges is to integrates a wide variety of serves, convey the more information as efficiently as possible through limited bandwidth and providing high data rates. Some of information bits are lost in most of the cases and signal which is sent originally will face fading. To reduce the bit error rate and signal fading require high data rate modulation ...
