Equivalence of Linear MMSE Detection in DS-CDMA and MC-CDMA Systems over Time and Frequency Selective Channels
The goal of this paper is to compare the performance of the linear minimum mean square error (MMSE) detector for a class of code division multiple access (CDMA) systems in time and frequency selective channels. Specifically, we consider direct sequence (DS)-CDMA, multicarrier (MC)-CDMA, and the MC-DS-CDMA systems. Two key tools are used in our development. First, a general time-frequency framew...
متن کاملPerformance of the MIMO-MC-CDMA System with MMSE Equalization
Multipath fading and spectral crowding are the major challenges in dealing higher data rate in future broadband wireless communication system. Multi-carrier Modulation like Multicarrier code division multiple access (MC-CDMA) can tackle the problem and provide higher data rate for future wireless communication system. However, through a frequency selective fading channel, the subcarriers in MC-...
متن کاملInterference Mitigation in MC-CDMA System with CFO compensation based Modified MMSE-FDE Technique
Multi-carrier Code Division Multiple Access (MC-CDMA) has been an attractive technique for wireless communication because it offers high data rate, high spectral efficiency, large system capacity, less transmit power and less implementation complexity. But due to Carrier Frequency Offset (CFO), which comes into account due to asynchrony between transmitter and receiver local oscillators or by D...
متن کاملIterative Multiuser Detection for DS-CDMA/MC-CDMA Powerline Communications
The increasing ubiquity of the Internet is creating a rapidly growing demand for larger bandwidth to the home. Currently the narrowband twisted-pair access network from an optical network unit (ONU) or a central office (CO) to a customer’s premises, the socalled “last dirty mile”, is the bottleneck for Internet traffic. The increasing demand for a home/office network further necessitates a flex...
متن کاملPerformance Improvement of MC-CDMA & CDMA using Smart Antenna Technique
Performance improves in terms of coverage in the MC-CDMA & CDMA network with the help of simulation model and an evaluation method for the smart antenna system is presented. The EC/Io coverage area is presented with the proposed method that can show the impact of smart antenna system on the function of antenna type and beam width. The performance improvements are remarkable in the smart antenna...
