The focus in this paper is on noncoherent combining of the outputs of the taps of the rake receiver in a code-division multiple-access (CDMA) system that employs DS spread spectrum with binary DPSK data modulation. It is shown that the a

Khandoker Tahmid Sami,Mohsen Tooranints due to the use of frequency hopping (FH) is initially reviewed followed by a brief summary of previously designed cellular/PCS systems that have incorporated FH methods. A recently designed slow frequency hop (SFH) prototype which was developed for PCS applications is then described. Performance

Efficient Secret Sharing Schemese scenario; and nonuniform capacity and non-uniform cell-size scenario. Due to the many variables, the number of channels in each cell has to meet certain conditions from the reverse channel formula. Then the total transmitted power of all the forward-link channels at each different cell site can be

Optimum PN Sequences for CDMA Systemse sequences for direct-sequence CDMA systems provide sequences that can be viewed as codewords (or the images of codewords) selected from low-rate Reed-Solomon codes. This chapter surveys sequence designs for CDMA systems from this viewpoint.

Interference Suppression for CDMA Overlays of Narrowband Waveformsmploy interference suppression filters in the CDMA receivers to minimize the interference caused by the narrowband waveforms. The results presented in this paper include the effects of multipath fading, as well as both intracell and intercell interference for cellular systems.

Secure Systems Development with UMLead-spectrum communications: the apparent increase in capacity when users become unsynchronized in a code-division multiple-access (CDMA) system and the fact that a heavily loaded CDMA system is as energy-efficient for transmitting information as a single-user system with the same (total) average po
