What is CSD (Cyclic Shift Delay)?

Cyclic shift diversity (CSD) is a technique of transmitter diversity. CSD is utilized and a cyclic delay is applied to the transmitted signals. The delays are determined to limit the connection between the numerous signals. A conventional legacy framework would treat the various received signals as multipath renditions of a similar signal. The cyclic delay is picked to be within the constraints of the guard interval (GI) so that it does not cause extreme intersymbol interference (ISI).
