Abstract

En 中文
An algorithm for the design of the overloaded complex spreading sequence sets on the uplink of multicell synchronous S-CDMA systems is introduced. Assuming that in each cell the number of active users K is greater than the corresponding processing gain N, the total weighted squared correlation (TWSC) criterion is used as a performance measure. The mathematical formalism is supported with selected numerical examples in the multicell context.
Keywords:
total (weighted) squared correlation
generalized Welch Bound Equality (WBE) sequences
