Application of Multicarrier CDMA to Mobile Communication Technology
نویسنده
چکیده
Modern cellular mobile system work on either the time division multiple access (TDMA) or code-division multiple access (CDMA) principle. In CDMA system every user is assigned a unique signature sequence to spread his information bearing signal over the available channel bandwidth irrespective of the information bandwidth. The signature sequence consists of a number of chips which is proportional to the symbol duration. This type of cellular transmission is known as direct-sequence (DS) spread spectum

Design of a Baseband Transceiver for Multicarrier CDMA Communications
Multicarrier systems have become popular for their spectral efficiency and robustness against frequency-selective fading. Multicarrier code-division multiple access (MC-CDMA) is a technique that combines the advantage of multicarrier modulation with that of code-division multiple access (CDMA) to offer reliable high-data-rate downlink cellular communication services. In this paper, we present t...
متن کاملA Robust Carrier Frequency Offset Estimation Algorithm in Burst Mode Multicarrier CDMA based Ad Hoc Networks
The future wireless communication systems demand very high data rates, anti-jamming ability and multiuser support. People want large amount of data to be continuously accessible in their personal devices. Direct Sequence (DS) spread spectrum based techniques such as Code Division Multiple Access (CDMA) fulfil these requirements but, at the same time, suffer from the Intersymbol Interference (IS...
متن کاملPerformance of asynchronous orthogonal multicarrier CDMA system in frequency selective fading channel
An asynchronous multicarrier (MC) direct-sequence (DS) code-division multiple-access (CDMA) scheme for the uplink of the mobile communication system operating in a frequency selective fading channel is analyzed. Bit error rate performance of the system with either equal-gain combining or maximum-ratio combining is obtained. Numerical results indicate that the system performs better than that of...
