The WWVB broadcast of the time-code signal has undergone no major changes in its communications protocol and modulation scheme since its introduction in 1963. [] Key Result The new protocol and modulation scheme being introduced by NIST effectively addresses these problems, and will enable greatly improved reception of the WWVB broadcast without affecting existing devices. This backward-compatibility is achieved by maintaining the existing AM characteristics while adding various new features through phase…

WWVB time signal broadcast: an enhanced broadcast format and multi-mode receiver

To improve the station's coverage, an enhanced broadcast format, based on the addition of phase modulation (PM), was deployed in 2012 and its enhanced features enable more reliable receiver performance and greater time-keeping accuracy at reduced power consumption.

Receiver Design of Radio-Controlled Clocks Based on the New WWVB Broadcast Format

The architecture and algorithms for the first all-digital radio-controlled clock receiver for the new WWVB broadcast format and two alternative timing synchronization approaches are investigated, showing that the correlation-based synchronization technique reduces the implementation complexity by over 50%, while its performance is only less than 1 dB inferior to that of the ML-based technique.

Interference-robustness improvement in BPSK receivers for the enhanced WWVB broadcast

An interference cancellation technique is proposed, to further enhance the performance of the coherent BPSK receiver, achieving an additional 14 dB improvement in interference rejection.

TIME AND FREQUENCY BROADCAST WITH DCF77

The advantages of DCF77, in particular its wide range of reception with low cost receivers, have led through the years to the use of millionsDCF77 radio-controlled clocks which provide exact time throughout central Europe.

A multi-mode software-defined CMOS BPSK receiver SoC for the newly enhanced WWVB atomic clock broadcast

The first receiver system-on-chip (SoC) for the newly enhanced phase-modulation based WWVB broadcast is presented and demonstrates 2-3 orders of receiver sensitivity superiority when compared to receiver ICs designed for the legacy WWVB Broadcast.

WWVB: A Half Century of Delivering Accurate Frequency and Time by Radio

A history of the National Institute of Standards and Technology (NIST) radio station WWVB is provided, from its origins as a source of standard frequency, to its current role as the source of time-of-day synchronization for many millions of radio controlled clocks.

Sequential Frame Synchronization Based on Hypothesis Testing With Unknown Channel State Information

This paper analytically shows that hypothesis testing can have better reliability and lower energy consumption than point estimation if the probability of false alarm of the hypothesis testing is lower than the minimum of two thresholds.

A new broadcast format and receiver architecture for radio controlled clocks

A digital receiver architecture, amenable to integration in a CMOS system-on-chip (SoC), is proposed, which relies on digital signal processing, thereby eliminating the need for the crystal filter and other passive components found in existing receivers.
