A wireless serving communication unit comprises a signal processor, for receiving and processing a signal to be broadcast, and a number of transmitters operably coupled to the signal processor, for transmitting the broadcast signal in a plurality of sectorised cells to a wireless subscriber communication unit. The wireless serving communication unit comprises logic to replicate the processed signal into a plurality of replicated signals and logic introduce one or more delay(s) to one or more of the replicated processed signals, such that replicated broadcast signals having different delays are transmitted from a plurality of sectorised cells to one or more wireless subscriber communication unit.
