FREQUENCY DEVIATION COMPENSATION SCHEME AND FREQUENCY DEVIATION COMPENSATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18351814 titled 'FREQUENCY DEVIATION COMPENSATION SCHEME AND FREQUENCY DEVIATION COMPENSATION METHOD

Simplified Explanation

The patent application describes a system for compensating for frequency deviation in a signal by using frequency shift. This compensation process can cause a phase offset between adjacent input blocks, leading to errors in the reconstructed bit sequence.

  • The system includes a frequency deviation compensation means that compensates for frequency deviation in a signal using frequency shift.
  • It also includes a phase offset compensation means that compensates for the phase offset caused by the frequency shift.
  • The purpose of the system is to ensure accurate reconstruction of the bit sequence by addressing the phase offset issue.
  • The system can be applied to a plurality of input blocks that are divided, allowing for compensation across multiple blocks.
  • The invention aims to improve the overall performance and reliability of frequency deviation compensation systems.


Original Abstract Submitted

When a frequency deviation compensation amount is compensated for by use of frequency shift, a phase offset occurs between adjacent input blocks included in a plurality of input blocks as divided, with the result that an error occurs in a reconstructed bit sequence. A frequency deviation compensation system of the invention is characterized by comprising: a frequency deviation compensation means for compensating for a frequency deviation occurring in a signal by use of frequency shift; and a phase offset compensation means for compensating for a phase offset occurring, in the signal, due to the frequency shift.
