Ronald Hugh Barker FIEE (1915 – 7 October 2015) was an Irish physicist and inventor of Barker code for digital synchronisation. He was a member of the Institution of Engineering and Technology (IET) for 70 years. Born in Dublin, Ireland to English parents, Barker excelled in mathematics, becoming keen on electronics. He is best known for his ground-breaking work on synchronising digital communication systems and framing of received data, using digital codes (see frame slip). These digital codes are known as Barker code. The method was initially researched at SRDE Royal Signals Research Establishment, just after World War II for use in radar, rocket telemetry and digital speech. In 1952, Barker found 7 Barker sequences up to a length of 13 useful for correlation. These sequences are widely
