Dc offset and bit timing system and method for use with a wireless transceiver

Abstract From the Canadian patent

An offset estimation and bit timing system and method. The inventive offset estimation system includes a first circuit for receiving and correlating a transmitted signal and generating a trigger signal in response thereto. A second circuit accumulates the received signal and provides a second signal on receipt of the trigger signal. The second signal is then converted to an offset error signal. In an illustrative implementation the offset estimation , system is implemented in a Bluetooth-enabled wireless receiver adapted to receive a signal transmitted with a known bit pattern. The received signal includes a plurality of messages, each message having at least one access code and …
