In this paper, we propose a hypothesis testing based sequential frame synchronization
technique that is robust against fluctuations and imperfect estimation of channel gain at the …

For over fifty years the Physikalisch-Technische Bundesanstalt (PTB) has disseminated time
signals and standard frequency by means of the low-frequency transmitter DCF77. In …

In commemoration of its 50th anniversary of broadcasting from Fort Collins, Colorado, this
paper provides a history of the National Institute of Standards and Technology (NIST) radio …

WWVB is a broadcast station, operated by the National Institute of Standards and
Technology, which has been broadcasting time information to radio-controlled clocks (RCC) …

The architecture and algorithms for the first all-digital radio-controlled clock receiver for the
new WWVB broadcast format are proposed. To address the potentially low signal-to-noise …

A new broadcast format is presented for the atomic-clock time-code signal broadcast by the
National Institute of Standards of Technology (NIST) from station WWVB in Fort Collins …

WWVB is a broadcast station, operated by the National Institute of Standards and
Technology, which has been broadcasting time information to radio-controlled clocks (RCC) …

Radio controlled clocks (RCCs) based on the WWVB broadcast, commonly referred to as
“atomic clocks”, might experience relatively high levels of on-frequency interference from the …

The first receiver system-on-chip (SoC) for the newly enhanced phase-modulation based
WWVB broadcast is presented. Having an extensively digital architecture, and relying on the …

WWVB timing signals have been broadcast from Fort Collins, Colorado since 1963. Starting
in the 1960s, oscillators disciplined by WWVB achieved frequency transfer below the 1× 10 …
