Abstract
An algorithm for the design of the overloaded complex spreading sequence sets on the uplink of multicellular synchronous CDMA systems is introduced. Assuming that in each cell the number of users K is greater than the corresponding processing gain N, the total weighted squared correlation criterion is used as a performance measure. The mathematical formalism is supported with selected numerical examples in the multicellular context.
