Abstract
A cordless telephone includes a base unit having a data generator which generates a digital data burst having a transition period, a data encoder which encodes the digital data burst, and a transmitter which transmits the encoded data burst; and a handset having a receiver responsive to and sampling the encoded data burst, and a synchronization device operatively coupled to the receiver for maintaining synchronization between the receiver and the transmitted encoded data burst in accordance with a characteristic of an expected time of transition of an incoming signal of the data encoder by comparing an actual time of transition to the expected time of transition and adjusting a sampling point of the transmitted encoded data burst by a one-sided majority vote of samples around the sampling point.
