A Study of Spread-Spectrum Multiple-Access Communications Over Fading Channels
… (DS) and slow-frequency-hopped (SFH) spread-spectrum multiple-access (SSMA) communications over fading channels is investigated. Nonselective, wide-sense-stationary uncorrelated-scattering time- or frequency-selective, and specular multipath fading channels are considered. Thermal …

Optimum linear single user detection in direct-sequence spread-spectrum multiple access systems
… proposal of the IS-95 standard, <i>code-division multiple access</i> (CDMA) gained popularity as an alternative multiple-access scheme in cellular and <i>personal communication systems</i> (PCS). Besides the advantage of allowing asynchronous operation of the users, CDMA <i>direct-sequence spread …

Spread spectrum satellite multiple access and overlay service
This thesis presents two applications of spread spectrum technology to very small aperture terminal (VSAT) satellite communication networks. It describes two spread spectrum multiple access systems which use a form of noncoherent M-ary FSK (MFSK) as the primary modulation and analyzes their …
