A Lattice Filter for CDMA Overlay
Code division multiple access (CDMA) implemented with direct sequence spread spectrum (DS-SS) is the most promising multiple accessing technique for cellular mobile communications systems. The spectral efficiency or spectral capacity of such a system is often inadequate as number of users increase. It has been proposed that CDMA systems can be assigned to spectral bands which are presently occupied by narrowband users to further increase the spectral capacity. Such CDMA overlay systems could provide an efficient utilization of spectrum with minimal disruption to existing narrowband users if additional signal processing techniques are employed in the CDMA receiver.英语论文网 【http://www.51lunwen.org】
