DECISION FEED FORWARD EQUALIZATION FOR PARTIAL RESPONSE EQUALIZED SIGNAL INCLUDING PRE-CURSOR CANCELATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18745229 titled 'DECISION FEED FORWARD EQUALIZATION FOR PARTIAL RESPONSE EQUALIZED SIGNAL INCLUDING PRE-CURSOR CANCELATION
The abstract describes a receiver system that includes a partial response (PR) system and a decision feed forward equalization (DFFE) system to equalize received signals from a transmitter over a channel, controlling the relationship between consecutive values of equalized received symbols and transmitted data.
- The receiver system includes a PR system that receives signals from the transmitter and equalizes them to establish a controlled relationship between received symbols and transmitted data.
- The DFFE system cancels pre-cursor and post-cursor intersymbol interference introduced by the channel, improving the overall signal quality.
- By equalizing the received signals and canceling ISI, the receiver system enhances the accuracy and reliability of the transmitted data.
- This technology is crucial for maintaining data integrity in communication systems, especially in scenarios where signal distortion is common.
- The receiver system's innovative design ensures efficient data transmission and reception, even in challenging channel conditions.
Potential Applications: - Telecommunications - Data transmission systems - Wireless communication networks
Problems Solved: - Intersymbol interference in communication channels - Signal distortion and degradation - Data accuracy and reliability issues
Benefits: - Improved signal quality - Enhanced data transmission accuracy - Reliable communication in adverse conditions
Commercial Applications: Title: Advanced Receiver Systems for Enhanced Data Transmission This technology can be utilized in various commercial applications such as: - Telecommunication companies - Networking equipment manufacturers - Satellite communication providers
Questions about the technology: 1. How does the DFFE system in the receiver help in canceling intersymbol interference? 2. What are the key advantages of using a PR system in the receiver for equalizing received signals?
Original Abstract Submitted
A receiver includes a partial response (PR) system that receives a received signal from a transmitter over a channel and equalize the received signal such that there is a controlled relationship between consecutive values of equalized received symbols and transmitted data transmitted by the transmitter. The receiver also includes a decision feed forward equalization (DFFE) system that receives partial response signals from the PR system and cancel at least one of pre-cursor intersymbol interference (ISI) or post-cursor ISI introduced by the channel.
