Multicarrier orthogonal CDMA signals for quasi-synchronous communication systems
We propose a multi-carrier orthogonal CDMA signaling scheme for a multiple-access communication system, such as the reverse channel of a cellular network, as an alternative to the multiuser interference cancellation approach. The average variance of cross-correlations between sequences is used as a measure for sequence design. We search for sets of sequences that minimize the probability of sym...
متن کاملPerformance of Orthogonal CDMA Codes for Quasi-Synchronous Communication Systems
In this paper, the performance of quasi-synchronous direct-sequence CDMA communication systems based on diierent sets of orthogonal codes is investigated. We search for sets of sequences that minimize the probability of bit detection error, given that there is imperfect synchronization among the signals. Orthogonal sequences based on the Sylvester-type Hadamard matrices (Walsh functions) are sh...
متن کاملPerformance Comparison of Orthogonal and Quasi-orthogonal Codes in Quasi-Synchronous Cellular CDMA Communication
Orthogonal and quasi-orthogonal codes are integral part of any DSCDMA based cellular systems. Orthogonal codes are ideal for use in perfectly synchronous scenario like downlink cellular communication. Quasi-orthogonal codes are preferred over orthogonal codes in the uplink communication where perfect synchronization cannot be achieved. In this paper, we attempt to compare orthogonal and quasi-o...
متن کاملEffects of carrier frequency accuracy on quasi-synchronous, multicarrier DS-CDMA communications using optimized sequences
It is known that the multiple access interference (MAI) of a quasi-synchronous (QS) multicarrier direct signal code division multiple access (DS-CDMA) system can be substantially reduced by using signature sequences having optimized cross correlation at small shifts around the origin. This paper shows that the time-frequency cross correlation function rather than the usual (time-domain) cross c...
متن کاملMulticarrier Orthogonal-CDMA for Fixed Wireless Access Applications
Recently, in the United States the FCC allocated a significant amount of bandwidth in different parts of the radio frequency spectrum for point-to-multipoint fixed wireless bidirectional communications. This includes parts of the 2 to 3 GHz bands, parts of the 5 to 6 GHz (known as U-NII) bands, and parts of the millimeter wave spectrum between 27 to 31 GHz (known as LMDS bands). In general, bro...
