Abstract :
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
