This abstract first appeared for US patent application 20240014953 titled 'METHOD FOR ESTIMATING BIT ERROR PROBABILITY USING ERROR RATE RATIO OF FRAME SYNCHRONIZATION WORD
Simplified Explanation
The present invention is a method for estimating the probability of bit errors in a communication system. The method uses the error rate ratio of a frame synchronization word to simplify the computational complexity, allowing for a relatively simple and economical implementation at a high computational speed.
- The method involves defining error rate ratios of frame synchronization words.
- A weighted least squares cost function is set with weights greater than or equal to 0, using the error rate ratios of the frame synchronization words.
- An estimated bit error probability value is obtained by minimizing the cost function.
- Sequentially obtaining the weights ensures that the mean squared error of the estimated bit error probability value becomes small.
Potential applications of this technology:
- Communication systems: The method can be applied in various communication systems, such as wireless networks, satellite communication, and optical communication, to estimate the probability of bit errors.
- Error correction: The estimated bit error probability can be used to optimize error correction techniques, improving the overall reliability and performance of the communication system.
Problems solved by this technology:
- Computational complexity: The method reduces the computational complexity involved in estimating the bit error probability, making it feasible to implement in simpler and more cost-effective systems.
- Speed: The method allows for high computational speed, enabling real-time estimation of bit error probabilities in fast-paced communication systems.
Benefits of this technology:
