Rate adaptive turbo forward error correction

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and apparatus for adaptive turbo forward error correction in high-speed communication systems. The invention enables efficient encoding and decoding of data at different rates and in multiple modulation formats (such as BPSK, QPSK, and 16QAM) by selectively activating encoder and decoder units according to the data rate. The system employs differential and turbo error correction techniques to enhance error correction with lower power consumption, supporting dynamic adaptation to various channel conditions and data speeds.

• High-speed optical fiber communications (e.g., data centers, long-haul networks)
• Wireless backhaul and core networks requiring adaptive data rates
• Data transmission systems needing robustness against noise and errors, such as satellite or undersea cable links
• Enterprise and service provider networks supporting varying bandwidth requirements
• Wireless communication systems (e.g., 5G/6G infrastructure) where channel conditions and data rates fluctuate

BenefitsContent extracted from patent full text and abstract with AI.

• Enables dynamic adaptation to multiple data rates and modulation schemes, improving flexibility and scalability
• Reduces power consumption by activating only necessary encoding/decoding units
• Enhances error correction performance, reducing data retransmission and increasing reliability
• Minimizes hardware complexity and space requirements, supporting integration into ASICs and compact devices

Patent Abstract

Techniques herein support enhanced multi-rate encoding and decoding of signals in multiple formats. In one embodiment, input data is received at a first device at one of a plurality of data rates. Encoder units are activated to produce streams of encoded input data. The encoder units are configured to operate at the same data rate. Differential encoding operations are performed to produce an encoded output stream. The encoded output stream is modulated for transmission to a second device. In another embodiment, a first device receives an encoded data stream that is transmitted from a second device. The modulated data stream includes encoded data at one of a plurality of data rates. Differential decoding is performed on the encoded data by activating one or more of a plurality of decoder units, where each of the plurality of decoder units is configured to operate at the same rate.
