  • Patent number: 5384828
    Abstract: A resynchronization method for use in a communication system, such as a second generation cordless telephone system 800, begins by determining that synchronization has been lost by a receiving unit (830). The receiving unit than mutes any transmit data and generates zero data which is combined with a pattern generated by pattern generator (812). The transmission is then received by handset (830), which detects the pattern generated by pattern generator (812) using pattern detector (850). Pattern detector (850) then generates a pattern detected signal (852) which causes handset (840) to also stop sending data and generate a pattern accompanied by zero data. Base station (830) detects the pattern and again generates another pattern accompanied with zero data which is transmitted to handset (840). Handset (840) after decoding the pattern for the second time begins to resumes the normal transmission of data to base station (830).
