AI Technical Summary

Technical Problem

In the existing technology, the PBCH demodulation performance in the 5G broadcast system is affected by the crystal oscillator deviation. The existing method has weak noise resistance and inaccurate frequency deviation estimation, resulting in degraded reception performance.

Method used

The frequency deviation range of the received signal is divided into multiple sub-intervals. PSS and SSS synchronization, as well as PBCH decoding, are performed separately in the sub-intervals of different levels. By predetermining the frequency deviation range and making detailed distinctions, synchronization and decoding performance are improved.

Benefits of technology

The PBCH demodulation success rate is improved, the requirement for receiver crystal oscillator accuracy is reduced, and the economic cost is reduced.
