BER Performance of Space-Time Coded MMSE DFE for Wideband Code Division Multiple Access (WCDMA)
In recent times, there has been growing interests in integration of voice, data and video traffic in wireless communication networks. With these growing interests, WCDMA has immerged as an attractive access technique. The performance of WCDMA system is deteriorated in presence of multipath fading environment. The paper presents space-time coded minimum mean square error (MMSE) Decision Feedback...
متن کاملBER Analysis of Wideband Code Division Multiple Access
There has been a dramatic change in the field of field of telelcommunication service. M-ary Quadrature Amplitude modulation and Quadrature Phase shift Keying (QPSK) modulation schemes are considered in Wideband code Division Multiple Access(WCDMA) system. Here we are using MATLAB for simulation and evaluation of BER ( Bit Error Rate )and SNR(Siganl to Noise Ratio). There is analysis of Quadratu...
متن کاملWideband Code Division and Multiplication Access
When we talk about first generation systems we think about analog cellular systems. The second-generation systems are GSM (Global System for Mobile Communication), PDC (Personal Digital Cellular, 2 nd generation system in Japan), cdmaOne (IS-95) and US-TDMA (IS-136). Third generation systems, which are designed for multimedia communication are to have high quality images and videos and to acces...

متن کاملCDMA – Code Division Multiple Access
Code Division Multiple Access (CDMA) is probably the most interesting multiple access method provided by spread spectrum technology. CDMA refers to a multiple access method in which the individual terminals use spreadspectrum techniques and occupy the entire spectrum whenever they transmit. This paper focuses on direct-sequence spread-spectrum principles (processing gain, spreading, de-spreadin...
