Blind Joint Soft-Detection Assisted Slow Frequency-Hopping Multicarrier DS-CDMA

, 2000
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 narrow-band ...
