Crest Factors of Complementary-Sequence-Based Multicode MC-CDMA Signals

, 2003
The crest factor properties of binary phase-shift keying modulated two- and four-code assisted multicarrier code-division multiple-access (MC-CDMA) employing complementary-sequence-based spreading sequences are characterized.

Fractionally Spread Multicarrier CDMA: A Multiple-Access Scheme for Various Wireless Channels

, 2003
In multicarrier code-division multiple-access (MCCDMA) the total system bandwidth is divided into a number of subbands, where each subband may use direct-sequence (DS) spreading and each subband signal is transmitted using a subcarrier frequency. In this

Slow Frequency-Hopping Multicarrier DS-CDMA for Transmission over Nakagami Multipath Fading Channels

, 2001
A novel multiple access scheme based on slow frequency hopping multicarrier direct-sequence code division multiple access (SFH/MC DS-CDMA) is proposed and investigated, which can be rendered compatible with the existing second-generation narrowband CDMA ...

Asymptotic Spectral-Efficiency of MIMO-CDMA Systems with Arbitrary Spatial Correlation

In this contribution, we analyze the asymptotic spectral-efficiency (ASE) of multiuser MIMO-CDMA systems, when assuming communications over flat fading channels with arbitrary spatial correlation.
