ABSTRACT:
A WLAN (Wireless Local Area Network) receiver having a synchronization unit is provided. The synchronization unit comprises a first functional unit for performing a first signal processing function, a second functional unit for performing a second signal processing function different from the first signal processing function, and at least one signal processing circuit. In the synchronization unit the first functional unit is operating at least one of the signal processing circuits for performing the first signal processing function, and the second functional unit is arranged for operating the at least one signal processing circuit operated by the first functional unit for performing the second signal processing function. Since the above-described signal processing circuits or modules can be re-used for the antenna diversity unit and the preamble detection unit this results in a smaller number of gates and an improved density of the circuitry.
