A Time Domain View to Multi-Carrier Spread Spectrum
نویسندگان
چکیده
Due to the success of DS-SS CDMA and OFDM in the early nineties, several approaches were developed to combine both schemes. Many papers which deal with multi-carrier techniques concentrate on signal processing in the frequency domain. This paper reviews research on time domain signal processing for multi-carrier spread-spectrum systems. Basic characteristics such as spectral shape, correlation behavior, and the need for a guard interval are discussed as well as questions about multiuser capability, receiver architectures, and implementation issues.

An Approach for a Multi-carrier Spread Spectrum System with Rake Receiver
Multi carrier spread spectrum is a new kind of modulation technique and can be viewed as the dual technique to direct sequence [1]. Hence many investigations have been focussing on detection in the frequency domain [2], [3]. However, we analyze the multi carrier spread spectrum (MC-SS) signal in the time domain. In out paper we compare time and frequency domain properties of both techniques, DS...
متن کاملOrthogonal Code-Multiplexed Frequency-Domain Single-Carrier Spread Spectrum
Abstract The authors have proposed a frequency-domain single-carrier spread spectrum (SC-FDSS) transmission technique, which achieves better bit-error rate (BER) and better power amplifier-dependent energy efficiency comparing with time-domain spread spectrum (TDSS). However, its wider transmission bandwidth leads to low spectrum efficiency, implying that a multiplexing technique is necessary. ...
متن کاملSingle-carrier Frequency-Domain CDMA
Abstract Single-carrier (SC) transmission is an appropriate transmission scheme for uplink transmission because of its low peak-to-average power ratio (PAPR). Spread spectrum (SS) transmission achieves higher frequency diversity gain and hence improves the bit error rate (BER) performance. The authors have recently proposed SC with frequency-domain spread spectrum (SC-FDSS) transmission with or...

Abstract Single-carrier (SC) transmission is a transmission equipped with frequency-domain equalization (FDE) is suitable for uplink transmission because of its low peak-to-average power ratio (PAPR) property. Square-root Nyquist filtering is widely used, where the filter shape is controlled by the roll-off factor from 0 to 1. Nyquist filtering with =1 occupies twice bandwidth of the origina...
متن کاملMulti-carrier Spread Spectrum Modulation with Reduced Dynamic Range
| Multi-carrier (MC) modulation has been recently proposed for code-division multiple access (CDMA) mobile radio communications, by modulating an identical symbol on multiple carriers of same magnitude. Certain phase o sets assigned to each carrier de ne a code that is given to a speci c user. We introduce a CDMA system based on multi-carrier spread spectrum (MC-SS) with one identical code for ...
